H.G.P. was founded in 1970 in Paris. Known for its diving equipment, the brand now crafts timepieces with a distinctive style and artisanal, high-quality manufacturing. Each model embodies adventure and elegance, pairing creative design with rugged materials. The Parisian brand is proud to introduce this H.G.P. Automatic Diver GMT 200m Watch - Vintage, a refined everyday companion for men. Its Monnin® barrel-shaped case measures 42 mm in diameter and 47 mm in length with a thickness of 13.20 mm, crafted from brushed and polished 316L stainless steel. It features a 120-click unidirectional bezel with a blue and red two-tone anodized aluminum insert bearing a SuperLuminova old radium marker and Arabic numerals on a 24-hour scale. The knurled edge surrounds a flat anti-reflective sapphire crystal treated on the inside, protecting the dial from shocks while ensuring glare-free reading. At 3 o'clock, a screwed and knurled crown provides easy control of the central functions. This model features 20 ATM water resistance, secured by its screwed and engraved caseback. It comes with a luggage tag and a blue canvas and brown bovine leather pouch for safe storage.
This dial is meticulously crafted for effortless, accurate timekeeping. It stands out with a slightly sandblasted black background adorned with silver-toned markers. The outer edge features a minute track and geometric hour markers. At the center, three silver hands ensure precise local time reading: the short hand marks the hours, the long hand the minutes, and the slim seconds hand tracks the elapsed seconds. A fourth red hand joins them, pointing to the GMT bezel for reading a second time zone. Like the indices, all hands are coated with SuperLuminova old radium treatment, ensuring optimal legibility in any conditions. For added functionality, a date window sits at 3 o'clock, with the country of manufacture at 6 o'clock. Above, the GMT function, water resistance rating, and movement type are noted, with the brand name placed below 12 o'clock as a signature.
Powering this watch is a reliable automatic movement - the Seiko NH34 caliber, of Japanese origin. Vibration-resistant and precise, it beats at a frequency of 21,600 vph, or 3 Hz, and features 24 jewels to minimize friction. This movement delivers a power reserve of 41 hours and is equipped with a hacking seconds function.
This watch comes with a choice of two straps, both featuring a lug width of 20 mm tapering to 16 mm at the buckle.
The first is crafted from 316L stainless steel, bringing a refined look to your wrist. Its brushed and polished links showcase a rice grain mesh construction for a bold, substantial appearance. Durable and comfortable, it makes for an easy all-day wear. With 5 micro-adjustment positions, it measures 210 mm in length and fits wrists up to 24.50 cm. Its sleek grey tone complements any outfit. The deployant clasp makes it a breeze to put on and take off, measuring 17.50 mm wide by 35 mm long.
The second Tropic strap features perforations that enhance its sporty character. Crafted from vulcanized rubber, it's flexible yet tough - perfect for physical and athletic activities. Its black tone pairs effortlessly with any look. Lightweight and comfortable to wear, the 316L stainless steel pin buckle lets you dial in the perfect fit. It measures 120 mm in length for the long end and 75 mm for the short end.
This model offers a water resistance of 20 atmospheres, or 200 meters - making it a watch that can keep up with your underwater adventures. Designed for freediving, it handles high-pressure washers without breaking a sweat. Showering, bathing, swimming, and freediving are all fair game. That said, for scuba diving with tanks, we recommend a timepiece with a higher water resistance rating. And remember: never operate the crown or pushers while submerged, to keep the movement fully protected.
