Proper 90s tool watch energy. Meet the Eterna Monterey reference 1630.41, a no nonsense chronograph powered by the legendary Valjoux 7750 movement. Reliable, easy to service, and built to take a beating. It features a 40mm stainless steel case, a white dial with a three-register layout and date, 120 meters of water resistance, and a screw-down crown. It’s in very good condition, with minor wear marks on the bracelet. The best part? The hangtag still shows the original retail price of $290,000 Portuguese escudos (approximately $1,750 or €1,500 in today’s money). That puts it firmly in serious money territory back in the 90s. Underrated brand, serious movement, and a cool bit of history attached. Hard to beat if you want a solid Swiss chrono without paying inflated money. Condition: Very good. Minor usage marks on the bracelet, which I did my best to photograph. The movement winds and resets properly, but I’m unsure of its service history. The sapphire crystal and anti-reflective coating are in perfect condition. Reference: 1630.41 Case Size: 40mm in stainless steel Movement: Valjoux 7750, automatic chronograph with date function.
