Best Watch Straps for the Tudor Black Bay 58

The Tudor Black Bay Fifty-Eight is the Black Bay that changed the conversation. When Tudor introduced it in 2018 the dial said "Fifty-Eight" and the case said 39mm — a deliberate return to the proportions of the original Tudor Submariner reference 7924 of 1958, the year the name references. At 39mm and 11.9mm thick it wears as the original Submariners did, before the gradual case inflation of the 1970s and 1980s that brought most dive watches to 41mm and beyond.

The BB58 sits between the BB54 and the BB41 in the Black Bay hierarchy. It is smaller and slimmer than the 41, thicker and more modern than the 54. The Super-LumiNova is white rather than the 54's gilt-toned beige. The crown guards are absent as on the 54. The result is a watch that reads as vintage in spirit but contemporary in execution — and one that has become, within a few years of launch, the most sought-after Black Bay in the collection.

Tudor has released the BB58 in an expanding range of variants: the original black dial, Navy Blue, Bronze, 925 sterling silver, and the S&G steel and gold. Each has a specific character and specific optimal strap palette.

Tudor Black Bay 58 Strap Size

Every Tudor Black Bay 58 uses 20mm lugs — confirmed by Tudor's official specifications across all variants. Standard spring bars throughout.

BB58 Black (ref. M79030N-0001, M79030N-0002) — 20mm. 39mm case, 11.9mm thick, 47mm lug-to-lug.

BB58 Navy Blue (ref. M79030B-0001, M79030B-0002) — 20mm. Same case dimensions.

BB58 Bronze (ref. M79012M-0001) — 20mm. 39mm bronze case.

BB58 925 Sterling Silver (ref. M79010SG-0001) — 20mm. 39mm 925 sterling silver case.

BB58 S&G Steel and Gold (ref. M79013MB-0001) — 20mm. Steel case with yellow gold accents.

The BB58 shares its 20mm lug width with the Black Bay 54, the Black Bay Pro, and the Ranger — the same strap fits all four.

The Factory Strap Choices — What Tudor's Editorial Says

Tudor ships the BB58 Black and Navy Blue on either the riveted steel bracelet or a single-pass fabric strap as standard options. The fabric strap is Tudor's own validation of the single-pass construction as factory-appropriate for the BB58. Tudor also offers a leather strap option on several BB58 configurations — confirming leather as a factory-endorsed material.

Best Rubber Straps for the Tudor Black Bay 58

Tropical style FKM in black at 20mm — the most historically resonant and most collector-celebrated BB58 combination. The vintage basket-weave and honeycomb surface patterns reference the 1950s and 1960s tropical rubber that dive watches of the 1958 reference era were worn on. The BB58's own 1958 heritage creates a direct connection to the original tropical rubber world — two objects from the same era, the watch and the strap, reunited.

Brown tropical FKM at 20mm — for the most warm and most aged vintage combination. Particularly effective on the BB58 Black where the warm brown against the black dial creates a temperature contrast that references original aged dive watch rubber directly.

Classic FKM rubber in black at 20mm — the most practical active choice for the BB58's 200m water resistance.

Variant-specific FKM recommendations:

BB58 Black — black tropical FKM for the most historically coherent combination; brown tropical FKM for warm vintage character
BB58 Navy Blue — blue FKM for tonal coherence; black tropical FKM for vintage collector character
BB58 Bronze — brown tropical FKM — warm rubber echoing the bronze case patina directly
BB58 925 — grey FKM for cool tonal coherence with the silver case

All at 20mm.

Best Nylon Straps for the Tudor Black Bay 58

Tudor ships the BB58 on a single-pass fabric strap as standard — directly validating the single-pass construction as the factory choice.

Single-pass nylon — Original at 20mm with the CNS solid buckle. Most appropriate BB58 colourways:

Black — the most minimal and most operationally coherent across all BB58 variants.
Navy — for the BB58 Navy Blue specifically. Creates direct tonal coherence with the blue dial and blue bezel insert.
Black and grey — the most understated collector combination for the BB58 Black.
Olive / khaki — for a military-adjacent operational character.
Admiralty Grey — the MOD-specification colourway referencing British naval dive watch heritage.

RAF single-pass nylon at 20mm — the RAF 6B/2617 specification was introduced in 1954 — four years before the Tudor reference 7924 of 1958 that the BB58 honours. Both the strap and the watch reference the same British military precision equipment world of the mid-1950s.

Marine Nationale elastic at 20mm — the most comfortable BB58 daily wear option. The French Navy combat swimmer connection — the same Nageurs de Combat who collaborated with Tudor on the Pelagos FXD — places the Marine Nationale strap directly in the Tudor naval diving heritage. Navy or black.

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

Best Leather Straps for the Tudor Black Bay 58

Tudor offers leather as a factory strap option on several BB58 configurations — validating leather as an appropriate material for a watch that is, despite its dive watch credentials, frequently worn in smart-casual and business contexts.

Brown vintage two-stitch calfskin at 20mm — the most celebrated BB58 leather combination and the most historically resonant. The warm brown and two-stitch construction reference 1958 — the year the original Tudor Submariner that names this watch was introduced. The BB58 Black on warm brown two-stitch leather creates a warm-cool contrast that is the most discussed BB58 leather pairing in the collector community. Tudor itself offers brown leather as a factory option, confirming this as the correct pairing.

Classic flat calfskin in dark brown at 20mm — the most versatile everyday leather. Flat construction suits the BB58's 11.9mm slim profile proportionally.

Classic black calfskin at 20mm — the most formal BB58 combination. The non-stitch variant is the most minimal. Black leather on the BB58 Black creates a unified dark palette where the white Super-LumiNova indices become the sole accent.

Navy calfskin at 20mm — for the BB58 Navy Blue specifically. Navy leather follows the dial and bezel colour in a tonal dress-sport combination that Tudor's own navy fabric strap validates.

Dark brown suede at 20mm — the most relaxed leather option for smart-casual contexts.

Tan suede at 20mm — for the BB58's most relaxed weekend character, referencing the warm leather equipment of 1950s diving culture.

The Bronze BB58 — Specific Strap Logic

The BB58 Bronze develops a natural patina over time, the bronze case gradually oxidising to warm green-brown tones. This creates a living material relationship with the strap.

Brown tropical FKM at 20mm — warm rubber that echoes the bronze at all stages of patina development.

Brown vintage two-stitch leather at 20mm — two materials that develop genuine character over time on the same wrist.

Tan suede at 20mm — warm earthy leather alongside warm earthy bronze.

What is the difference between the BB54 and BB58 for straps? Both use 20mm standard spring bars — the same strap fits both.
