100x more reliable that the Jetstar you're thinking of. Here's a review by Just One More Watch for your consideration. Yes it's a quartz movement, but that seconds hand is something to behold.
Diameter: 40 mm
Lug-to-lug: 45 mm (!!!)
Lug width: 20 mm
Water resist: 50 m
Crystal: Single-domed sapphire
A great price for a Jet Star watch, although I'm rather more partial to the 97B214. This is the same 262KHz quartz found in the Lunar Pilot. It's amazingly accurate and you'll probably never need to set the time again.
