VK63A Chronograph Quartz Movement with Battery (VK63 / VK61A / VK67A Series): Which One Your Case Actually Takes

When a quartz chronograph stops, the first question is never which movement to buy - it is whether the movement is the problem at all. Work through it in order: if the watch runs slow, stops intermittently or the chronograph hands refuse to reset, the usual first suspect is the battery, and this listing does include a battery, so a dead cell is the cheapest thing to rule out. If a fresh battery changes nothing - no tick, no reset, no chronograph - then the movement is the likely fault and replacing it is usually cheaper than a full service. This is where you have to be careful, because the title deliberately lists three related movements: VK63, VK61A and VK67A. They belong to the same family, but the sub-dial layout and date window position are not identical, so a movement that fits one case will not necessarily line up in another. Before ordering, note down your case model and confirm with the seller which of those variants it takes, plus the movement diameter and thickness, the dial feet position and the hand sizes your watchmaker will need. Fitting a movement means pulling and refitting the hands, so budget for a watchmaker, a dust-free workspace and a new gasket if the old one is compressed - and expect water resistance to need re-testing afterwards.

30.8mm Quartz Chronograph Movement with Single Calendar: When a Watch Stops, Runs Wrong or the Chrono Hand Will Not Reset - and How to Check the Fit

A quartz watch that stops, runs slow, or has a chronograph hand that no longer resets to twelve is usually telling you one of three things, and working out which one decides whether you need a whole movement or just a battery. If the seconds hand jumps once a second, the battery is flat - a new cell cures it. If the watch runs but is badly fast or slow, or the chronograph pushers do nothing, the movement's oscillator or the reset mechanism is the suspect, and that is where a replacement movement like this 30.8mm quartz chronograph comes in. If the hands and date are fine but there is corrosion or a dark patch on the dial near the crown, water has probably got in, and the movement is the least of the problems. To confirm a swap is the right fix, compare your old movement against this one: measure the diameter (30.8mm is a standard chronograph size), note the thickness, and check where the date window sits - a single calendar at 4:30 or at 3 o'clock, because the dial hole has to line up. Hand-fitting diameters and the winding stem height decide whether your existing hands and case will work. Movements of this class run at 32,768 Hz and usually take a 394 / SR936SW-type button cell, but confirm the cell type on your old movement rather than assuming. Fitting one needs hand-lifting tools, a stem to cut, and a dust-free bench, so if you have never done a swap, a watchmaker's labour charge is often cheaper than a scratched dial.
