Is the Citizen Nighthawk worth it?

A true GMT — the local hour hand jumps independently, which is the version travelers actually want — with sapphire, 200m and a published 47mm lug-to-lug at 39.5mm.

Mechanical, so it needs servicing eventually, and Baltic sells direct so we earn nothing on this link.

Baltic states the Miyota 9075 is a true GMT — the local hour hand jumps independently — which is rare at this level. Add a double-domed sapphire crystal, a sapphire 24-hour bezel, a screwed crown and 200m in a 39.5mm case. Sold direct; we earn nothing on it.

The specification the Nighthawk is missing: sapphire rather than mineral, plus radio-controlled timekeeping so it sets itself, with the same five-year warranty and 200m rating.

45mm across, so a considerably larger watch, and Citizen publishes no lug-to-lug for it either.

It sets itself by radio, runs on light and is rated to 200m behind sapphire — and it is a module, not a movement. When the module stops being made, the watch is finished, however good the case still is.

A mechanical GMT at a price that used to be impossible, on the 4R34, with the same $176 published service path as every other 4R.

Hardlex, 100m, and a caller-type GMT rather than a true one — the 24-hour hand moves, not the local hand.

The 4R34 is a caller GMT — the 24-hour hand is the one you set, not the local hand — but it is a real mechanical second time zone on a movement whose service price Seiko publishes.

Sapphire, 200m, world time and a chronograph, radio-set, on the same five-year warranty.

A 23mm lug width, which is the hardest strap size to buy on this site.

Sapphire, 200m, a perpetual calendar and a chronograph that runs on light — and a 23mm lug width, which is the least common strap size on this site. It is a module rather than a movement, so its long-term future depends on Citizen continuing to support the H800.

Light-powered, so there is no battery to change and no winding — put it in a drawer for a month and it is still right. Over twenty years there is essentially nothing to spend on it.

A genuine second time zone plus a slide-rule bezel, rated 200m in a 42mm case, with Citizen's five-year limited warranty — the longest cover of any brand this site rates.

The mineral crystal is the real cost: it marks permanently where sapphire would not, on a watch otherwise specified well above that. And Citizen publishes no lug-to-lug, thickness or lug width, so fit and strap changes are both guesswork until it arrives.

200m, five years of cover and a second time zone from a watch you never wind, service or open. The mineral crystal is the cost, and on a 42mm slab of glass it is a cost you will eventually see.
