Nothing else at this price offers sapphire, a screw-down crown, 15 ATM and a stated two-year warranty at once, and the Miyota 8215 inside it is the single most commonly serviced automatic caliber there is — which means a watchmaker in any town has seen one and can quote on it without opening the case first.
Spinnaker also publishes the number that decides whether you can give it, and we would rather you knew: 51mm lug-to-lug, the longest footprint on this site by a clear margin. On a wrist under about seven inches it will overhang.
Who it is for: a recipient whose wrist you know is large, or whose current watch you can measure. Who should skip it: anybody you are guessing about — and anybody who will wear it occasionally, because it is an automatic and will be stopped every time they pick it up.
Against it: 13mm thick on top of the long footprint, and Spinnaker publishes no service price for the caliber. The 22mm lug width is standard and easy to shop for.
Sapphire, 15 ATM, a screw-down crown and a stated two-year warranty on a Miyota 8215 — a caliber every independent has seen. Then Spinnaker publishes the lug-to-lug: 51mm, the longest on this site by a clear margin.
