Dive rated to 100M\/300ft, it is the lowest-profile titanium-cased button compass available anywhere. No batteries. No signal. No circuit board. Just the earth's magnetic field, housed in one of the toughest non-magnetic metals on the planet.\u003c\/p\u003e\n\u003ch3\u003eWhat is the history of the wrist compass?\u003c\/h3\u003e\n\u003cp\u003eThe wrist compass traces directly to the underwater demolition teams (UDTs), combat swimmers, and special operations divers of the mid-20th century, operators who needed a compact, hands-free directional instrument that functioned underwater and in zero-visibility conditions. By the Cold War era, wrist-mount compasses were standard kit for combat divers, paratroopers, and special reconnaissance units across NATO forces. The format was trusted precisely because it required nothing but the earth's magnetic field: no batteries to die, no signal to lose, no electronics to fail under pressure or in the cold. PDW's EWBCK 2.0 is a direct descendant of that lineage, purpose-built for the modern explorer, overlander, and adventurer who understands that analog tools don't fail when digital ones do.\u003c\/p\u003e\n\u003ch3\u003eWhy is the case made from titanium?\u003c\/h3\u003e\n\u003cp\u003eAerospace-grade 6AL-4V titanium is non-magnetic, non-corroding, and pound-for-pound stronger than steel. For a compass, non-magnetic construction is not optional, it is the entire point. A steel case would interfere with the compass needle and degrade accuracy. Titanium eliminates that problem entirely while delivering a case that resists saltwater, perspiration, abrasion, and impact without adding meaningful weight. At 0.30oz\/8.50g total, the EWBCK 2.0 is built to last a lifetime without ever interfering with the instrument it protects.\u003c\/p\u003e\n\u003ch3\u003eWhat watch bands does the EWBCK 2.0 fit?\u003c\/h3\u003e\n\u003cp\u003eThe EWBCK 2.0 fits 20mm and 22mm NATO-style watch bands and Marine Nationale Para (MN Para) closed-loop elastic bands. The split-back case design is the key engineering detail that makes MN Para compatibility possible. Closed-loop bands cannot be threaded the traditional way, so the split back allows the compass to mount without removing the strap. It also slides cleanly over standard NATO nylon straps. Compatible with tool watches from Tudor, Seiko, Panerai, Rolex, and any watch with 20mm or 22mm lug width.\u003c\/p\u003e\n\u003ch3\u003eIs the EWBCK 2.0 waterproof?\u003c\/h3\u003e\n\u003cp\u003eYes. The EWBCK 2.0 carries a 100M\/300ft water resistance rating, dive-rated and amphibious by design. Whether you are surf fishing, packrafting, on a combat dive, or caught in a downpour on the trail, it performs. The threaded two-piece titanium construction seals the oil-filled button compass against ingress at depth. Wear it in anything.\u003c\/p\u003e\n\u003ch3\u003eHow accurate is an oil-filled button compass?\u003c\/h3\u003e\n\u003cp\u003eThe EWBCK 2.0 uses an oil-filled button compass with a luminous glow-in-the-dark dial and an orange accent north triangle for fast orientation in low light. Oil-dampened compasses suppress needle oscillation, allowing faster and steadier readings than dry-needle designs, which is why they are the format of choice in dive, military, and expedition contexts. Accuracy is sufficient for land navigation, trail bearing work, and open-water heading reference. Note: like all oil-filled compasses, small air bubbles may appear and disappear with changes in altitude or barometric pressure. This is normal and has no effect on accuracy or function.\u003c\/p\u003e\n\u003ch3\u003eCan I swap out the compass element for something else?\u003c\/h3\u003e\n\u003cp\u003eYes, and no tools required. One of the significant upgrades in the 2.0 is the ability to change out the compass element without any tools. Swap in PDW's optional A.G. button thermometer in Fahrenheit or Celsius to convert the case into a wrist thermometer in seconds. Swap back to the compass just as fast. Same titanium case, different instrument. Form follows function.\u003c\/p\u003e\n\u003ch3\u003eWhat are the four silicone carriers included with the kit?\u003c\/h3\u003e\n\u003cp\u003eEvery EWBCK 2.0 ships with all four silicone carrier colors: OD green, gray, orange, and glow-in-the-dark (GID). The OD green, gray, and orange versions include UV inhibitors to prevent fading in the field. The GID carrier activates in low light. The silicone carriers expand carry options beyond the watch band: girth-hitch the compass to pack webbing, D-rings, sternum straps, shoulder straps, or gear loops. The orange carrier signals high visibility in water, alpine, and search-and-rescue environments. All four are included.\u003c\/p\u003e\n\u003ch3\u003eWhy carry an analog compass when my phone has GPS?\u003c\/h3\u003e\n\u003cp\u003eGPS requires a satellite signal, battery power, and a functioning device. A magnetic compass requires none of these. It works in dense canopy, underground, underwater, at altitude, in a whiteout, and when your phone is dead, broken, or out of signal. The magnetic compass transformed navigation for centuries before the first circuit board existed. For anyone operating in high-consequence environments, overland expeditions, backcountry travel, water-based navigation, or preparedness situations, redundancy is not paranoia, it is protocol. The EWBCK 2.0 is the backup that never needs charging and never loses signal. It simply works.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the TIP, Matte and PVD versions?\u003c\/h3\u003e\n\u003cp\u003eAll three versions share identical construction, materials, specs, and performance. The TIP version featured a \"polished\" case finish intended to be a match to cases finished as found in Rolex and Tudor Submariners. Matte version features a fine matte-finished 6AL-4V titanium case, the natural look of industrial-grade tools and well matched to tool watches like the Sinn U-Series, the MKII Paradvies, and Tudor FXD. The PVD version applies a Physical Vapor Deposition coating for a deep black finish that reduces visual signature and pairs with all-black or stealth-configured tool watch setups. PVD is harder than bare titanium and adds an additional layer of scratch resistance. Choose the finish that best matches your watch case.\u003c\/p\u003e\n\u003ch3\u003eWhat tool watches pair well with the PDW EWBCK 2.0?\u003c\/h3\u003e\n\u003cp\u003eAny tool watch with 20mm or 22mm lugs. Strong pairings include Tudor Black Bay, Tudor Pelagos FXD, Seiko SKX and 5 Sports series, Panerai Luminor, Rolex Explorer and Submariner, MKII Paradive to Fulcrum, the Sinn U-Series, and HGP. The split-back design was specifically engineered to solve the MN Para closed-loop problem that made previous wrist compasses incompatible with one of the most popular modern military watch straps. If it has 20mm or 22mm lugs and a strap worth wearing, the EWBCK 2.0 belongs on it.\u003c\/p\u003e\n\u003ch3\u003eWhat is Prometheus Design Werx?\u003c\/h3\u003e\n\u003cp\u003ePrometheus Design Werx (PDW) is a U.S.-based independent design studio founded in the San Francisco Bay Area, producing purpose-built EDC gear, technical apparel, and expedition-grade tools for overlanders, adventure travelers, and self-reliant individuals who operate far from the ordinary. Every product PDW designs is one the team uses themselves, in the field, in the water, on the road. The EWBCK was created because PDW recognized that no wrist compass existed that was worthy of a serious tool watch or a serious mission. The result set the standard from the beginning, and from where all others follow.

Dive rated to 100M\/300ft, it is the lowest-profile titanium-cased button compass available anywhere. No batteries. No signal. No circuit board. Just the earth's magnetic field, housed in one of the toughest non-magnetic metals on the planet.\u003c\/p\u003e\n\u003ch3\u003eWhat is the history of the wrist compass?\u003c\/h3\u003e\n\u003cp\u003eThe wrist compass traces directly to the underwater demolition teams (UDTs), combat swimmers, and special operations divers of the mid-20th century, operators who needed a compact, hands-free directional instrument that functioned underwater and in zero-visibility conditions. By the Cold War era, wrist-mount compasses were standard kit for combat divers, paratroopers, and special reconnaissance units across NATO forces. The format was trusted precisely because it required nothing but the earth's magnetic field: no batteries to die, no signal to lose, no electronics to fail under pressure or in the cold. PDW's EWBCK 2.0 is a direct descendant of that lineage, purpose-built for the modern explorer, overlander, and adventurer who understands that analog tools don't fail when digital ones do.\u003c\/p\u003e\n\u003ch3\u003eWhy is the case made from titanium?\u003c\/h3\u003e\n\u003cp\u003eAerospace-grade 6AL-4V titanium is non-magnetic, non-corroding, and pound-for-pound stronger than steel. For a compass, non-magnetic construction is not optional, it is the entire point. A steel case would interfere with the compass needle and degrade accuracy. Titanium eliminates that problem entirely while delivering a case that resists saltwater, perspiration, abrasion, and impact without adding meaningful weight. At 0.30oz\/8.50g total, the EWBCK 2.0 is built to last a lifetime without ever interfering with the instrument it protects.\u003c\/p\u003e\n\u003ch3\u003eWhat watch bands does the EWBCK 2.0 fit?\u003c\/h3\u003e\n\u003cp\u003eThe EWBCK 2.0 fits 20mm and 22mm NATO-style watch bands and Marine Nationale Para (MN Para) closed-loop elastic bands. The split-back case design is the key engineering detail that makes MN Para compatibility possible. Closed-loop bands cannot be threaded the traditional way, so the split back allows the compass to mount without removing the strap. It also slides cleanly over standard NATO nylon straps. Compatible with tool watches from Tudor, Seiko, Panerai, Rolex, and any watch with 20mm or 22mm lug width.\u003c\/p\u003e\n\u003ch3\u003eIs the EWBCK 2.0 waterproof?\u003c\/h3\u003e\n\u003cp\u003eYes. The EWBCK 2.0 carries a 100M\/300ft water resistance rating, dive-rated and amphibious by design. Whether you are surf fishing, packrafting, on a combat dive, or caught in a downpour on the trail, it performs. The threaded two-piece titanium construction seals the oil-filled button compass against ingress at depth. Wear it in anything.\u003c\/p\u003e\n\u003ch3\u003eHow accurate is an oil-filled button compass?\u003c\/h3\u003e\n\u003cp\u003eThe EWBCK 2.0 uses an oil-filled button compass with a luminous glow-in-the-dark dial and an orange accent north triangle for fast orientation in low light. Oil-dampened compasses suppress needle oscillation, allowing faster and steadier readings than dry-needle designs, which is why they are the format of choice in dive, military, and expedition contexts. Accuracy is sufficient for land navigation, trail bearing work, and open-water heading reference. Note: like all oil-filled compasses, small air bubbles may appear and disappear with changes in altitude or barometric pressure. This is normal and has no effect on accuracy or function.\u003c\/p\u003e\n\u003ch3\u003eCan I swap out the compass element for something else?\u003c\/h3\u003e\n\u003cp\u003eYes, and no tools required. One of the significant upgrades in the 2.0 is the ability to change out the compass element without any tools. Swap in PDW's optional A.G. button thermometer in Fahrenheit or Celsius to convert the case into a wrist thermometer in seconds. Swap back to the compass just as fast. Same titanium case, different instrument. Form follows function.\u003c\/p\u003e\n\u003ch3\u003eWhat are the four silicone carriers included with the kit?\u003c\/h3\u003e\n\u003cp\u003eEvery EWBCK 2.0 ships with all four silicone carrier colors: OD green, gray, orange, and glow-in-the-dark (GID). The OD green, gray, and orange versions include UV inhibitors to prevent fading in the field. The GID carrier activates in low light. The silicone carriers expand carry options beyond the watch band: girth-hitch the compass to pack webbing, D-rings, sternum straps, shoulder straps, or gear loops. The orange carrier signals high visibility in water, alpine, and search-and-rescue environments. All four are included.\u003c\/p\u003e\n\u003ch3\u003eWhy carry an analog compass when my phone has GPS?\u003c\/h3\u003e\n\u003cp\u003eGPS requires a satellite signal, battery power, and a functioning device. A magnetic compass requires none of these. It works in dense canopy, underground, underwater, at altitude, in a whiteout, and when your phone is dead, broken, or out of signal. The magnetic compass transformed navigation for centuries before the first circuit board existed. For anyone operating in high-consequence environments, overland expeditions, backcountry travel, water-based navigation, or preparedness situations, redundancy is not paranoia, it is protocol. The EWBCK 2.0 is the backup that never needs charging and never loses signal. It simply works.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the TIP, Matte and PVD versions?\u003c\/h3\u003e\n\u003cp\u003eAll three versions share identical construction, materials, specs, and performance. The TIP version featured a \"polished\" case finish intended to be a match to cases finished as found in Rolex and Tudor Submariners. Matte version features a fine matte-finished 6AL-4V titanium case, the natural look of industrial-grade tools and well matched to tool watches like the Sinn U-Series, the MKII Paradvies, and Tudor FXD. The PVD version applies a Physical Vapor Deposition coating for a deep black finish that reduces visual signature and pairs with all-black or stealth-configured tool watch setups. PVD is harder than bare titanium and adds an additional layer of scratch resistance. Choose the finish that best matches your watch case.\u003c\/p\u003e\n\u003ch3\u003eWhat tool watches pair well with the PDW EWBCK 2.0?\u003c\/h3\u003e\n\u003cp\u003eAny tool watch with 20mm or 22mm lugs. Strong pairings include Tudor Black Bay, Tudor Pelagos FXD, Seiko SKX and 5 Sports series, Panerai Luminor, Rolex Explorer and Submariner, MKII Paradive to Fulcrum, the Sinn U-Series, and HGP. The split-back design was specifically engineered to solve the MN Para closed-loop problem that made previous wrist compasses incompatible with one of the most popular modern military watch straps. If it has 20mm or 22mm lugs and a strap worth wearing, the EWBCK 2.0 belongs on it.\u003c\/p\u003e\n\u003ch3\u003eWhat is Prometheus Design Werx?\u003c\/h3\u003e\n\u003cp\u003ePrometheus Design Werx (PDW) is a U.S.-based independent design studio founded in the San Francisco Bay Area, producing purpose-built EDC gear, technical apparel, and expedition-grade tools for overlanders, adventure travelers, and self-reliant individuals who operate far from the ordinary.

While we can use to great effect and marvel at the products of our digital age, there is still something substantial to be respected, acknowledged and said for analog and mechanical devices. The invention and introduction of the magnetic compass transformed the known world. Unreliant on batteries or circuit boards, a magnetic compass is the directional navigation tool in its most distilled and purest form. Our design process to create this modern classic drew inspiration from similar wrist compass units as used and worn by UDTs, Combat Swimmers, Explorers and Adventurers from a different era.
