I have a few vintage replacements salvaged from otherwise unservicible modules. There are no current sources for the original style parts. Motorola [the original manufacturer] stopped making this type of crystal in the early 80s. The much smaller, cylindrical 32.768KHz crystals will work [as they are the correct frequency], but the adjustment trimmer may have restricted range because the smaller crystals have a different circuit capacitance [in the interest of keeping the watch as original as possible, I prefer to use a vintage replacement part]. This is not a complex repair. Crystal only, tested good, $25. Installed, with timing adjustment [guaranteed to meet or exceed the original 60sec/year tolerance], $40, + round-trip postage [typically $8, Priority Mail].
