Frequently asked questions

What lug width is the Steinhart Ocean One?

The Steinhart Ocean 1 Premium 500 (42mm) uses a 20mm lug width. The Ocean 39 Vintage Diver uses 19mm. The GMT Premium (42mm) uses 20mm. The Marine Automatic (44mm) uses 22mm. For the core Ocean One — the most commonly owned Steinhart — 20mm is the correct width. 20mm gives the Ocean One the same enormous AliExpress strap selection as the Rolex Submariner: thousands of rubber, NATO, sailcloth, and leather options.

What's the best cheap strap for the Steinhart Ocean One?

The Steinhart Ocean One is a serious dive watch with a Submariner-adjacent aesthetic — rubber and dive straps are the most authentic choices. FKM rubber in 20mm at $8–$15 from AliExpress is the top pick. The Ocean One's brushed and polished steel case suits matte black rubber best — avoid glossy rubber that looks cheaper than the Steinhart's finish deserves. Tropic-style perforated rubber at $6–$12 gives it a vintage dive character. Sailcloth at $10–$18 is a premium-feeling alternative. The Steinhart community on Reddit (r/SteinhartWatches) frequently discusses strap options — many use the same straps commonly recommended for the Submariner.
