100m on a dress watch is the specification that makes this the pick. Every other watch on this page is 30m or 50m, which means the recipient has to learn and remember a rule. This one they can simply wear.
The quick-release bracelet is the second reason and it is unusual at this level: the bracelet comes off and a strap goes on in about thirty seconds with no tool at all. For a gift that is worth a lot — if the bracelet is the wrong size or not their taste, the problem solves itself for the price of a strap.
Tissot publishes a $210 US price for a complete mechanical service, which almost no maker at this level does. Who it is for: a graduation, a new job, a fortieth birthday, a recipient who wears a watch to the office. Who should skip it: somebody who wants the thinnest possible watch — at 11.5mm this is a dress watch you can wear every day rather than a formal-only one.
Against it: the 21mm lug width, which is the awkward size, and Tissot publishes no lug-to-lug figure for this reference. Two years of warranty is shorter than the Japanese makers give.
The quick-release bracelet is the detail worth paying for: this is one of the few Swiss automatics at this level you can re-strap in thirty seconds without a tool.
