Best Watch Straps for the Steinhart Ocean One
Best Watch Straps for the Steinhart Ocean One
The Steinhart Ocean One is the watch that built the brand. When Günter Steinhart introduced the Ocean One in the early 2000s, the idea was straightforward: a Swiss Made dive watch with a Submariner-inspired design, a Sellita or ETA movement, sapphire crystal, 300m water resistance, and solid bracelet construction — sold directly from manufacturer to customer at a price that made the specification genuinely accessible. The Ocean One has been Steinhart's flagship ever since, evolving through multiple generations and variants while maintaining the same fundamental brief.
At 42mm with a 50.5mm lug-to-lug and 13mm thickness, the Ocean One wears larger than the Ocean 39 — the straight lug design means the lug-to-lug measurement wears on the wrist rather than curving away from it. This is a characteristic of the design rather than a flaw — it gives the Ocean One a strong, purposeful wrist presence that the collector community associates with the watch's operational character.
The Ocean One range covers more variants than any other Steinhart collection: standard black, blue, and green dial versions; ceramic bezel upgrades; vintage military references; Comex homages; titanium cases; and GMT complications. All 42mm and 44mm Ocean One variants share the same 22mm lug width.
Steinhart Ocean One Strap Size
The Steinhart Ocean One uses 22mm watch straps lugs — confirmed directly by Steinhart's own OEM bracelet specification ("22x18mm, matches all Ocean 1 and Ocean 44 models with 22mm lug size") and Steinhart's own technical specifications ("Lug width: 22mm"). 42mm case, 13mm thick, 50-50.5mm lug-to-lug.
Ocean One 42mm (all dial colours and bezel variants) — 22mm watch straps. Ocean One 44mm (all variants) — 22mm watch straps. Ocean One Vintage Military — 22mm watch straps. Ocean One Comex — 22mm watch straps. Ocean One Titanium 500 Premium — 22mm watch straps. Ocean One GMT variants — 22mm watch straps. All Ocean One 42mm and 44mm variants — 22mm watch straps.
Important note on incorrect information: Some online sources incorrectly list the Steinhart Ocean One as 18mm. This is wrong — Steinhart's own OEM bracelet and technical specifications confirm 22mm across all Ocean One 42mm and 44mm references. Order 22mm watch straps.
The Ocean 39 uses 20mm — not the same as the Ocean One. See the Steinhart Ocean 39 guide for the smaller variant.
The Ocean One Variant Range
The Ocean One family is Steinhart's most extensive — understanding which variant you own helps identify the most appropriate strap choices.
Standard diver variants (black, blue, green bezels): Classic dive watch brief. Rubber and nylon primary. Leather creates the most surprising transformation.
Vintage Military: Black dial, pencil hands, no date, Mil-Sub-inspired. The most operationally specific variant. Nylon and canvas suit the military brief directly.
Comex: The Comex homage with orange crown and signed dial. Bold colour accent creates specific strap pairing opportunities.
Ceramic bezel variants: Higher specification versions. Any material works — the ceramic bezel's durability matches any strap's active use requirements.
Titanium 500 Premium: Lightweight titanium case. The reduced weight makes rubber and elastic straps particularly comfortable.
GMT variants: Dual time zone. Aviation-adjacent heritage suits leather and nylon equally.
Best Rubber Straps for the Steinhart Ocean One
Tropical style FKM in black at 22mm watch straps — the most celebrated Ocean One rubber combination. The vintage basket-weave and honeycomb patterns reference the professional dive watch culture the Ocean One draws from directly. Black tropical FKM on the black dial Ocean One creates a unified dark vintage combination.
Brown tropical FKM at 22mm watch straps — the most warm and most specifically vintage-aged combination. Particularly effective on the blue bezel variants where warm brown creates a striking temperature contrast.
Classic FKM rubber in black at 22mm watch straps — the most practical active upgrade from the factory bracelet.
Blue FKM rubber at 22mm watch straps — for the blue bezel variants. Tonal coherence between rubber and bezel.
Orange FKM rubber at 22mm watch straps — for the Comex variant specifically. The Comex's orange crown is directly referenced by an orange rubber strap — a bold, internally coherent combination.
Best Nylon Straps for the Steinhart Ocean One
Single-pass nylon — Original at 22mm watch straps with the CNS solid buckle. Most appropriate Ocean One colourways:
- Black — the most minimal and most operationally coherent for all black dial variants
- Navy — for the blue bezel variants. Tonal coherence between strap and bezel
- Olive / khaki — for the Vintage Military variant specifically. The Mil-Sub heritage and military brief suit olive nylon directly
- Admiralty Grey — the most composed operational colourway
- Black and grey — the most understated collector combination
Marine Nationale elastic at 22mm watch straps — the most comfortable Ocean One daily wear option. The French Navy professional dive heritage connects directly to the Ocean One's own 300m specification. The elastic construction is particularly comfortable given the Ocean One's 50.5mm lug-to-lug.
RAF single-pass nylon at 22mm watch straps — for the most specifically European military heritage combination.
Canvas at 22mm watch straps in olive — for the Vintage Military variant. Canvas suits the Mil-Sub heritage directly.
Paratrooper elastic at 22mm watch straps — the most comfortable daily option.
Best Leather Straps for the Steinhart Ocean One
Leather transforms the Ocean One from a tool watch into a compelling sport-dress piece. The large 42mm case wears leather differently from the Ocean 39 — the added presence means leather reads as a deliberate statement rather than a refinement.
Leather watch straps in dark brown at 22mm watch straps — the most celebrated Ocean One leather combination. Warm brown against the brushed steel case and black dial creates the warm-cool contrast that is the most consistently discussed Ocean One leather pairing. The Vintage Military variant on dark brown leather specifically references the operational leather of the Mil-Sub era.
Leather watch straps in black at 22mm watch straps — the most formally correct combination across all variants.
Leather watch straps in tan suede at 22mm watch straps — the most relaxed leather option. Warm tan suits the black dial Ocean One in a casual dress-sport register.
Leather watch straps in navy at 22mm watch straps — for the GMT and blue bezel variants. Tonal coherence between navy leather and blue bezel in a formal register.
Leather watch straps in dark brown suede at 22mm watch straps — for smart-casual contexts across all variants.
The Steinhart Cluster
Steinhart Ocean 39 — 20mm watch straps. The 39mm variant. Different lug width — not interchangeable with the Ocean One.
