【Vintage-Inspired Jumping Hour Mechanism】 A classic jump hour watch with vintage character, powered by the Seagull ST1721 mechanical movement. Unlike traditional hands, this watches displays the hour in a window, jumping precisely at each hour change. Important – Time Setting: Always advance the minute hand clockwise only. Do not turn the minute hand counterclockwise, as this may damage the movement.
【Classic 39mm Size for Daily Wear】 39mm case, 20mm genuine leather strap. Total watch length is 260mm, fitting wrists from 160mm to 200mm comfortably. Real wrist test (180mm): The buckle sits at the middle hole, with 3 spare holes on each side – easy to adjust for a looser or tighter fit.
【Jumping Hour Characteristic (Normal Behavior)】 Due to the gear function of the Seagull movement, the hour may sometimes jump at 57 minutes instead of exactly 60 minutes. This is normal and does not affect accuracy or functionality.
【Premium Materials – Sapphire Crystal & 316L Steel】 Scratch-resistant AR-coated sapphire crystal, 316L stainless steel case, and screw-down crown. Built for daily wear with 50M water resistance (rain, sweat, splashes – not for swimming).
