I'm selling this Mondaine Stop2Go to fund another purchase. The watch is in like new. I only wore it 2-3 times. Comes with full kit and additional strap. The Mondaine Stop2Go is a unique and captivating watch that pays homage to the iconic Swiss Railway Clocks. With its Mondaine Cal. 58-02 quartz movement, the watch features a distinctive pausing and resuming of the seconds hand, creating a captivating and charming experience. The watch's design, including its bold black markers, simple white dial, and tip-heavy red seconds hand, is both simple and powerful. The actual Stop2Go complication functionality is an homage to a novel quirk that’s shared amongst iconic Swiss Railway Clocks all around the country. First introduced in the 1940s, the Swiss engineer responsible for the clock’s original functionality had to ensure that supreme accuracy and (most importantly) synchronization across all Swiss Railway Clocks. This synchronization is achieved by attuning all Swiss Railway Clocks to a master clock. Therefore, the iconic pausing and resuming of Swiss Railway Clocks is the result of the time it takes for the clock to complete a full minute rotation and then the time it takes for the clock to receive the signal from the master clock that it’s time to start the next full minute rotation. The Cal. 58-02 is unique in that it has two individual motors within it (as opposed to one, which is common among quartz movements). One motor controls the seconds hand and then other motor controls the hour and minute hand. The watch is programmed to actually run slightly fast in order for the second hand to reach the 12 o’clock position 2 seconds faster than normal (58 seconds). When the second hand motor reaches the 12 o’clock position at 58 seconds, it then allows the hour and minute hand motor to take 2 seconds to move by clicking to the next minute, recreating the iconic movement of the Swiss Railway Clocks as they receive the signal from the designated master clock. The other unique feature of this Stop2Go movement is that it has a clean seconds hand sweep as opposed to the anticipated ticking motion of quartz movements. This is achieved because the the seconds hand motor is programmed to tick 4 times every second as opposed to ticking once ever second. By ticking 4 times every second, it recreates a clean sweeping motion. # Mondaine Stop2Go Specs **Case:** 41mm x 48mm x 12mm **Lug Width:** 20mm **Movement:** Mondaine Cal. 58-02 Stop2Go Quartz **Crystal:** AR coated sapphire **Water Resistance:** 30m **Case Material:** Stainless Steel I'm asking **$525** shipped CONUS.
