Best Watch Straps for the Oris Divers Sixty-Five

Best Watch Straps for the Oris Divers Sixty-Five

The Oris Divers Sixty-Five is the most faithful vintage dive watch reissue in current production. Where most watch brands reinterpret their vintage references with updated case geometry, modern finishing, and contemporary proportions, Oris took a different approach with the Sixty-Five: reproduce the original 1965 design as closely as modern manufacturing allows, including the domed bubble sapphire crystal that mimics acrylic, the aluminium bezel insert that references mid-1960s bezel construction, the applied Arabic numerals in blocky typeface, and the vintage-toned lume that looks as though it has naturally aged. The result is a watch that, unlike most vintage reissues, actually looks vintage at a distance and in photographs.

The original watch that inspired it — Oris's own 1965 diver — was produced during the first era of serious recreational diving, when the sport was growing rapidly and purpose-built diving instruments were being developed by Swiss watchmakers in response to genuine demand from divers rather than collectors.

Oris Divers Sixty-Five Strap Sizes — Lug Width by Case Size

The Divers Sixty-Five uses different lug widths for each case size. Always identify your specific case size before ordering.

Divers Sixty-Five 40mm (ref. 01 733 7707 4035-07, 01 733 7707 4053-07 and all current 40mm variants including Calibre 400) — 20mm lugs. The most widely owned and most recommended Sixty-Five size. 48mm lug-to-lug, 13mm thick. Quick-release spring bars standard.

Divers Sixty-Five 42mm (ref. 01 733 7720 4055-07 and all 42mm variants) — 21mm lugs. Quick-release spring bars standard.

The Factory Tropical Rubber Strap — Oris's Own Validation

Oris ships the 40mm Divers Sixty-Five on a tropical-style rubber strap as standard. The textured weave surface directly references the Tropic brand straps of the 1960s that dive watches of the original Sixty-Five era were worn on. CNS's tropical style FKM at 20mm follows this factory logic in a material construction that CNS specifies and controls.

Best Rubber Straps for the Oris Divers Sixty-Five 40mm

Tropical style FKM in black at 20mm — the most historically resonant and factory-validated combination for the Sixty-Five. Oris ships the watch on a tropical rubber strap as standard, confirming this as their own editorial choice. The vintage basket-weave and honeycomb surface patterns reference the 1960s Tropic-brand straps that the original 1965 Oris diver was worn on.

Brown tropical FKM at 20mm — for the most aged and most specifically vintage combination. The warm brown tropical rubber mimics the oxidation of original 1960s dive watch rubber. Particularly effective on the navy blue dial Sixty-Five where warm brown creates temperature contrast with the cool blue.

Classic FKM rubber in black at 20mm — the most practical active choice for swimming and water activities.

Dial-specific FKM recommendations:

Navy blue dial — black tropical FKM for vintage collector aesthetic; brown tropical FKM for warm vintage contrast
Black dial — black tropical FKM for unified vintage palette
Green dial — green FKM for tonal coherence; black tropical FKM for collector aesthetic
Silver / white dial — grey FKM for cool tonal coherence; black tropical FKM for vintage contrast
Bronze case references — brown tropical FKM for warm coherence with the bronze patina

All at 20mm.

Best Nylon Straps for the Oris Divers Sixty-Five 40mm

Single-pass nylon — Original at 20mm with the CNS solid buckle. Oris ships the Sixty-Five on a woven fabric strap as an option on several references — directly validating the single-pass construction as factory-appropriate. Most appropriate Sixty-Five colourways:

Black — the most minimal. Suits all dial colours.
Navy — for the blue dial references. Creates tonal coherence with the most iconic Sixty-Five dial.
Olive / khaki — for the most vintage expedition-adjacent aesthetic.
Black and grey — the most understated collector combination.

Marine Nationale elastic at 20mm — the most comfortable Sixty-Five daily wear option. The French Navy combat swimmer heritage connects to the same 1960s professional diving world the Sixty-Five celebrates. Navy or black.

RAF single-pass nylon at 20mm — for the most specifically military-heritage operational combination.

Paratrooper elastic at 20mm — the most comfortable daily option.

Best Leather Straps for the Oris Divers Sixty-Five 40mm

Leather on the Sixty-Five creates the most dramatic transformation available — the vintage rubber dive watch becomes a refined dress-sport piece. Oris sells the 40mm Sixty-Five on a brown leather strap as a primary alternative to rubber, confirming leather as factory-appropriate.

Brown vintage two-stitch calfskin at 20mm — the most characterful Sixty-Five leather combination and the most historically resonant. The warm brown and two-stitch construction reference the 1965 era of the original watch. The warm brown against the navy blue dial creates a warm-cool contrast that is the most discussed Sixty-Five leather pairing in the collector community.

Classic flat calfskin in dark brown at 20mm — following Oris's own factory leather pairing in a full-grain material that ages genuinely. The most versatile everyday leather for the Sixty-Five.

Classic black calfskin at 20mm — the most formal combination.

Tan suede at 20mm — the most relaxed leather option. References the worn leather equipment of 1960s diving culture in a warm, casual register.

Dark brown suede at 20mm — for smart-casual and weekend contexts.

The 38mm and 42mm — Specific Notes

38mm (19mm): The 38mm Sixty-Five is the most directly proportional to the original 1965 watch. Brown vintage two-stitch leather at 19mm is the most period-correct combination. Tropical FKM at 19mm for the most vintage active pairing. The 38mm's slim 12mm thickness suits flat rather than padded constructions.

42mm (21mm): The 42mm Sixty-Five uses a non-standard 21mm lug width that limits most aftermarket options. CNS stocks the full range at 21mm. Brown vintage two-stitch at 21mm and tropical FKM at 21mm are the primary recommendations.

Recommended Combinations

40mm — most factory-validated — black tropical FKM at 20mm — matching Oris's own factory strap choice.

40mm — most celebrated leather — brown vintage two-stitch calfskin at 20mm — the blue dial and brown leather sweet-spot combination.

40mm blue dial — most vintage — brown tropical FKM at 20mm — warm aged rubber against cool blue dial.

Bronze references — most coherent — brown tropical FKM at 19mm or 20mm — warm brown rubber echoing bronze patina.

38mm — most period-correct — brown vintage two-stitch leather at 19mm.

42mm — most comfortable active — Marine Nationale elastic at 21mm.
