A GMT hand, a ceramic bezel and a 200 meter rating used to mean a four-figure invoice. San Martin lists the SN0136-G-GMT at $328 to $380, in a 39mm case.
The measurements are sensible rather than svelte. 13.5mm thick and 47.5mm lug to lug on a 39mm case, so it wears a touch tall for its width, but the 20mm bracelet carries a fly-adjustable clasp, which is the feature the SPB143 entry scolds Seiko for leaving out. Sapphire with AR coating, a 120-click ceramic bezel, 200 meters. The dial comes in matte black, sunray blue, sunray green and dark brown.
The engine is an NH34, which San Martin calls a Japanese automatic. That is a workable, common GMT caliber, and the price tells you not to expect finishing. San Martin publishes no power reserve, so I will not quote one from memory.
I think it is the sensible way into dual-time watches: cheap enough that a mistake costs little. If you never cross a time zone, a Citizen NY0086 is the better diver for similar money. If you do, this is the one to price against everything else.
