Description

I’ve got this Seiko mod Sea Dweller 43mm built up recently, and I’m happy to share it if you’re into something solid and stylish. The dial’s a deep blue to black with a silver Mercedes-style hand and a red second hand — looks sharp. Date window is there, and the uni-directional dive bezel is a nice touch. Case and oyster bracelet are polished and brushed 316L stainless, with a micro slide clasp so you can adjust it a bit more easily. It’s got a screw-down crown, solid end links, and screw-in pins — feels sturdy and built to last. The watch is 43mm and 17.5mm thick, so it’s not just a pretty face — it’s an impact watch. All the parts are new or original, and it runs on the Seiko NH35 movement.

I’ve been keeping it in my collection for a while now, and it’s been a real joy to work on. If you’re interested, just let me know — happy to chat about it or show you a quick photo. It’s based in west-mersea, Colchester.
