Diver 200M Chrono-Mecaquartz Big Eye

HGP's first chronograph in over fifty years, the Diver 200M Chrono-Mecaquartz Big Eye brings the brand's French dive heritage to a new complication. Built around the iconic Monnin 664 case — the same architecture behind early Heuer, Breitling, and Sinn dive pieces — and powered by the Seiko VK64 mecaquartz, it delivers a 1/5th-second sweep chronograph with quartz accuracy and a no-compromise dive spec. Seven layers of Swiss C3 Super-LumiNova across the dial and skeletonized hands ensure the Big Eye is as readable below the surface as it is above.

At 38.5mm across the bezel, 42mm lug-to-lug, and 12.4mm thick, the Chrono-Mecaquartz wears tighter than most tool chronographs at this price — compact enough for daily use, purposeful enough for the water. A screw-down crown with crown guards and screw-down caseback lock in 200 meters of water resistance, while the flat sapphire crystal and unidirectional bezel keep the profile honest. The "Big Eye" dial puts a large 30-minute sub-dial at 6 o'clock alongside a 24-hour display, with a rectangular lollipop chronograph hand and broad-arrow minute hand that are period-correct for a French tool watch.

The Seiko VK64 gives the watch the feel of a mechanical with the reliability of quartz — accurate to ±20 seconds per month, with a 3-year battery and hacking seconds for precise synchronization. Paired with a black rally "Tropic" rubber strap and assembled in Besançon by HGP's French watchmaker partner MNP, this is a grab-and-go dive chronograph with fifty years of professional lineage behind the case.
