Frequently Asked Questions
What does HGP stand for?
HGP stands for Hommes Grenouilles de Paris, which translates as "Frogmen of Paris." HGP was a Paris-based dive equipment shop active from the 1970s through the 1990s that commissioned dive watches under its own name from French and Swiss watchmaking partners. The brand was revived in 2023 by the Wolbrook Watch Company and is now assembled in France near Besançon.
What is a Monnin case and why does it matter?
The Monnin case is a dive watch case architecture engineered in the mid-1970s by French case maker Georges Monnin, originally for Heuer's entry into the dive watch market. The case design proved so capable that it was subsequently adopted under contract by Breitling, Sinn, Aquadive, Zodiac, and HGP, among others. It is one of the few dive watch cases known to collectors by its maker's name rather than the brand printed on the dial. The SPD x HGP Diver 200M uses the original Monnin case architecture.
What movement does the SPD x HGP Diver 200M use?
The watch is powered by a Seiko NH38 non-date automatic movement, a workhorse Japanese mechanical caliber known for reliability and serviceability. It features hacking seconds, hand winding, a 41-hour power reserve, and runs at 21,600 vibrations per hour. Each movement is regulated and quality-checked in-house by HGP's watchmakers in France to a tolerance tighter than the Seiko factory baseline.
Where is the SPD x HGP Diver 200M assembled?
The watch is assembled by hand in France at the MNP Solutions Horlogères workshop in Pierrefontaine-les-Varans, in the Franche-Comté region. This is the historic heartland of French watchmaking, near Besançon. Each watch undergoes individual control, assembly, regulation, and final quality check by trained French watchmakers before shipping.
Is the SPD x HGP Diver 200M suitable for scuba diving?
Yes. The watch is rated to 200 meters / 20 ATM water resistance, with a screw-down crown and screw-down caseback, and a unidirectional 60-click dive bezel for tracking elapsed bottom time. It is suitable for recreational scuba diving, free diving, snorkeling, and any water-based activity. Routine pressure testing every two to three years is recommended for any mechanical dive watch in active use.
How is this watch different from the standard HGP Commando Diver 200M?
The SPD Edition is an exclusive PDW Special Projects Division collaboration. It carries the SPD Kraken Trident at twelve in discreet Covert Gray on the dial, the signature SPD orange sweep seconds hand, and the SPD logo and wordmark engraved on the caseback. Production is limited to the SPD Edition run and the watch is sold exclusively through Prometheus Design Werx.
What straps will fit this watch?
The Diver 200M has a 20mm lug width with quick-release spring bars. It is compatible with all PDW Ti-NATO straps in 20mm, as well as any standard 20mm strap or bracelet. The watch ships with an exclusive, signature colorway of our Ti-MNPara strap and the Expedition Watch Band Compass Kit 2.0.
Is this a limited edition?
Yes. The SPD x HGP Diver 200M Automatic is currently a limited production collaboration.
