Citizen Mini Tsuyosa 60 Automatic 37mm NK0030-51X

The Citizen Mini TSUYOSA 60 NK0030-51X is the aquamarine one — and on this watch, colour does more work than usual. The compact 37mm stainless steel case carries a clean aquamarine tone dial with a guilloche concentric finish, so the pattern catches light progressively as the wrist moves and the surface shifts between deep forest and a brighter, warmer green depending on the angle. Silver-tone accents pick out the hands and markers against it, a date window sits at three o'clock, and an anti-reflective sapphire crystal covers the whole face with scratch resistance mineral glass cannot match. The seamlessly integrated five-link jubilee bracelet flows straight out of the case with no visible lugs, which is what gives this design its clean, unbroken profile on the wrist.

Inside is Citizen's calibre 8310 — a 21-jewel automatic wound by the motion of your arm, beating at 21,600 vibrations per hour, with no battery to replace at any point in its life. The 60-hour power reserve is what the "60" in the name refers to, and it changes how the watch fits a week: take it off Friday evening and it will still be running Monday morning.

A hacking seconds function stops the seconds hand when the crown is pulled so the time can be set precisely, and the watch is water resistant to 50 metres. This is a 37mm aquamarine green-dial automatic watch with an integrated steel bracelet and sapphire crystal for someone who wants genuine Japanese mechanical watchmaking in a classically sized, unisex case — discreet enough for the office, distinctive enough that people ask about it, and backed by Citizen's five-year limited warranty.

What we love about this watch: Green is the most requested dial colour in watchmaking right now and the hardest to get right — too bright and it looks novelty, too dark and it reads black. The Mini TSUYOSA 60 NK0030-51X lands it, and the textured dial is the reason: the pattern gives the green somewhere to go as the light changes, so it stays interesting in a way a flat sunray green never does. Same 60-hour automatic movement and sapphire crystal as the black version, at a size that suits a normal wrist.
