Atlas notes

Plenty of budget GMTs lean on a coloured bezel to do the talking. The SN0054-G-B1 does without one: San Martin’s listing specifies a 316L steel bezel, a matte black or matte white dial, and a $299 price, marked down from a listed $459.

The numbers are tidy. 39mm across, 12.4mm thick, 20mm lugs, a top hat sapphire crystal with AR coating, and a bracelet that tapers to 16mm and closes on a folding clasp with a safety catch and four micro-holes. The NH34 is the GMT movement inside; the page gives no power reserve, and I will not supply one from memory.

The weak points are plain. Water resistance is 100 meters, so this is a travel watch, not a dive watch. The lug to lug is 48.5mm, long for a 39mm case, and it will wear larger than the diameter implies on a small wrist. The listing gives 143g, which is no featherweight either. And the page does not say what the dial prints, so I will not describe it.

Worth a look, then, and a better fit than the SN0109 if you dislike a colour bezel. If you want a quick-adjust clasp, check that first: this page lists micro-holes, not a fly-adjust system. For that, the SN0109 is the one to buy.
