Best Watch Straps for the Seiko SKX007
Best Watch Straps for the Seiko SKX007
The Seiko SKX007 is the most modded watch ever made — not the most expensive, not the most technically complex, but the one that has inspired more aftermarket customisation, more strap experimentation, and more community discussion than any other watch in history. Since its introduction in 1996 and until its discontinuation in 2019, the SKX007 was the entry point to serious dive watch ownership for an entire generation of collectors. It remains so today, through the secondhand market, at prices that have risen from the original retail but remain accessible.
The design brief is spare and functional: a 42.5mm stainless steel case with a crown at 4 o'clock, a screw-down crown providing 200m water resistance, an ISO 6425-certified unidirectional rotating bezel, a black dial with luminous indices and hands, and a 7S26 automatic movement visible through the exhibition caseback. The case combines satin-brushed top surfaces with high-polished flanks. Worn & Wound's review described it as "a natural progression of the design going back several models" — the SKX007 is not a revolution but a refinement of a lineage that goes back to the 62MAS of the 1960s.
The SKX007 accepts strap changes more readily than almost any other watch. Drilled lugs make spring bar replacement straightforward with a fork tool. The 22mm lug width is the most commonly stocked width in the aftermarket. The black dial responds to every material and every colour. This is why the SKX007 became the defining strap-changing watch of the collector world.
Seiko SKX007 Strap Size
The Seiko SKX007 uses 22mm watch straps lugs — confirmed by Worn & Wound ("lug width is 22mm"), Strap Mill Canada ("22mm lug width"), BespokeUnit ("strap size between the lugs to be 22mm"), and namokiMODS. 42.5mm case, 13.25mm thick, 46mm lug-to-lug. Drilled lugs.
SKX007K1 (rubber strap) — 22mm watch straps. SKX007K2 (Jubilee bracelet) — 22mm watch straps. SKX007J (Japan-market rubber strap) — 22mm watch straps.
All SKX007 references use 22mm watch straps drilled lugs. The SKX013 uses 20mm — not interchangeable.
Why the SKX007 is the Strap-Changer's Watch
Three properties make the SKX007 the canonical strap-changing watch:
Drilled lugs. The lug walls have through-holes — a fork spring bar tool passes through the hole rather than needing to navigate between the strap end and the case side. Strap changes are faster and more reliable than on most watches.
22mm lug width. The most widely stocked strap width in the aftermarket. Every material, every style, every colour is available at 22mm. The SKX007 never limits your options.
Black dial. A black dial works with every strap colour without contradiction. Warm leather, cool navy nylon, bright orange rubber — nothing clashes. The SKX007 is a blank canvas that rewards any strap choice the owner makes.
Best Rubber Straps for the Seiko SKX007
Seiko ships the SKX007K1 on rubber as standard — rubber is the primary dive watch material and the most historically appropriate for the SKX007's operational brief.
Tropical style FKM in black at 22mm watch straps — the most celebrated SKX007 combination in the collector community. The vintage basket-weave and honeycomb surface patterns reference the same 1960s dive watch culture as the SKX007's design lineage. Black tropical rubber on the black dial creates a unified dark vintage combination that remains the canonical SKX007 aftermarket strap after decades of community experimentation.
Brown tropical FKM at 22mm watch straps — for the most warm and most specifically vintage-aged character. The warm brown tropical on the black dial creates a temperature contrast that mimics the oxidation of original 1960s dive watch rubber.
Classic FKM rubber in black at 22mm watch straps — the most practical active upgrade from the factory rubber. The premium FKM material is waterproof, chemical-resistant, and UV-stable in a way the factory rubber cannot match.
Grey FKM rubber at 22mm watch straps — for a composed, modern combination with the brushed steel case.
Orange FKM rubber at 22mm watch straps — for the most visually striking SKX007 active combination. Orange rubber on black dial is a bold, purposeful choice in the tradition of dive watch rescue colouring.
Best Nylon Straps for the Seiko SKX007
Single-pass nylon — Original at 22mm watch straps with the CNS solid buckle. The SKX007's black dial works with every nylon colourway. Most recommended combinations:
- Olive / khaki — the most specifically military dive and expedition character. The SKX007's operational brief suits olive nylon directly.
- Black — the most minimal. Unified dark palette.
- Navy — for a maritime, diving-heritage combination.
- Admiralty Grey — for the most MOD-specification operational colourway.
- Black and grey — the most understated collector combination.
- Orange — for the boldest and most safety-colour-referencing combination, pulling the dive rescue palette onto the strap.
Marine Nationale elastic at 22mm watch straps — the most comfortable SKX007 daily wear option. The French Navy combat swimmer heritage connects directly to the SKX007's own professional dive specification. Navy or black.
RAF single-pass nylon at 22mm watch straps — for the most specifically British military heritage combination.
Canvas at 22mm watch straps in olive — for a vintage expedition diver character.
Paratrooper elastic at 22mm watch straps — the most comfortable daily option.
Best Leather Straps for the Seiko SKX007
Leather on the SKX007 is the transformation that most surprises new owners. The same watch that sits on a rubber dive strap in the morning becomes a compelling sport-dress piece on brown leather in the afternoon. The black dial's neutrality means leather reads as a considered choice rather than a mismatch.
Brown vintage two-stitch calfskin at 22mm watch straps — the most celebrated SKX007 leather combination. The warm brown and two-stitch construction reference the 1968 dive watch era that the SKX's design lineage draws from. On the black dial, warm brown creates a warm-cool contrast that is the single most photographed and most discussed SKX007 aftermarket leather pairing across every watch community. Worn & Wound identified leather as one of the key versatility features of the SKX — "the watch changes character entirely depending on what it sits on."
Dark brown padded calfskin at 22mm watch straps — the most substantial everyday leather for the SKX007's 13.25mm case thickness.
Classic flat calfskin in black at 22mm watch straps — the most formal SKX007 combination.
Tan suede at 22mm watch straps — the most relaxed leather option. Warm tan against the black dial creates a casual dress-sport character.
Dark brown suede at 22mm watch straps — for smart-casual and weekend contexts.
Navy calfskin at 22mm watch straps — for a composed maritime formal combination.

Frequently Asked Questions
What size strap does the Seiko SKX007 take? 22mm watch straps — confirmed by Worn & Wound, Strap Mill Canada, BespokeUnit, and namokiMODS. All SKX007 references use 22mm drilled lugs.
What is the best strap for the Seiko SKX007? Black tropical style FKM at 22mm watch straps — the most celebrated and most historically coherent combination, referencing the 1960s dive watch rubber culture the SKX007's design lineage draws from. Brown vintage two-stitch leather for the most celebrated dress-sport transformation.
Does the SKX007 have drilled lugs? Yes — the SKX007 has drilled lugs with through-holes in the lug walls. A fork spring bar tool passes through the hole for straightforward strap changes. This is one of the SKX007's practical advantages over watches with non-drilled lugs.
What is the difference between the SKX007 and SKX009 for straps? Both use 22mm watch straps — the same straps fit both. The strap logic differs: the SKX007's black dial accepts any colour without contradiction. The SKX009's navy blue dial and Pepsi bezel create specific colour relationships — warm brown creates contrast, navy creates coherence, red accents reference the bezel.
