Best anniversary watch gifts

A Presage dress dial on a Prospex specification: dual-curved sapphire, 100m, a 72-hour 6R5J with a published +25/-15 seconds a day, and Seiko's three-year warranty.

13mm thick — it will sit on a cuff rather than under it.

This is the Presage with the Prospex specification sheet: dual-curved sapphire, 100m, 72 hours and a published +25 to -15 seconds a day, on the 6R family's published $296 service path. It is 13mm thick, which is the price of all that on a dress watch.

An 80-hour Swiss automatic with sapphire and 100m, on a bracelet that swaps to leather in thirty seconds for the evening.

The open heart shows the balance wheel; the Le Locle below is the plain-dial alternative.

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.

A skeletonized 80-hour automatic under sapphire with a 42mm lug-to-lug — a watch whose movement is part of the gift.

Rated 50m.

42mm lug-to-lug on a 40mm case is remarkable — this is a skeleton watch that actually fits a normal wrist. 50m is the honest limit: an open dial is still a sealed case, but it is not a watch to swim in.

An 80-hour Swiss automatic at 35mm with sapphire and 100m, backed by Tissot's published $210 service price.

The integrated bracelet's 11mm fitting is not a strap size.

An 80-hour Swiss automatic at 35mm with sapphire and 100m, backed by Tissot's published $210 service price. The integrated bracelet is the long-term trade — an 11mm fitting is not a strap size, so you keep the bracelet the watch came with or you keep nothing.

Under 10mm with sapphire and an 80-hour Powermatic 80 — the plain, thin dress watch that will look the same in twenty years.

Rated 30m; keep it out of the shower.

Under 10mm thick with 80 hours of reserve is the combination that makes a dress watch practical — put it down on Friday and it is still running Monday. 30m means keep it off in the shower.

The Cocktail Time's dial is the reason people give it, and it runs on the 4R35 with a published $176 overhaul and three years of warranty.

A box-shaped Hardlex crystal rather than sapphire, and 50m.

The same 4R35 and the same $176 published overhaul as the rest of the Cocktail Time line, with the lug-to-lug published — 47.5mm — so you can check the fit before buying. 50m and Hardlex are the dress-watch trade.
