Best Watch Straps for the Orient Kamasu
Best Watch Straps for the Orient Kamasu
The Orient Kamasu is the third generation of Orient's Mako diver — the watch that established Orient as a credible affordable dive watch manufacturer when the original Mako launched in 2004. The Kamasu refines the Mako formula with a sapphire crystal, an updated case profile, and the F6922 in-house automatic movement. At 41.8mm with a 47mm lug-to-lug and 12.8mm thickness it is a properly proportioned dive watch — large enough to read clearly underwater, slim enough to wear under a shirt cuff.
"Kamasu" is the Japanese word for Barracuda — a fitting name for a watch whose triangular hour markers and arrow-tipped hands reference the fish's distinctive teeth. The 120-click unidirectional bezel with its dotted minute pattern between bold numerals is one of the more distinctive bezel designs in the affordable diver category. The day-date complication at 3 o'clock continues the Mako tradition of practical legibility over minimalism.
Orient ships the Kamasu on a solid-link bracelet with a push-button deployant clasp and hollow end links. The bracelet is functional but the hollow end links create a slight gap at the lug that the collector community consistently identifies as the Kamasu's weakest element. The aftermarket strap opportunity is significant — Orient produces its own OEM 22mm rubber strap for the Kamasu, confirming rubber as the primary aftermarket material.

The Kamasu Colour Logic — Six Dial Variants
The Kamasu's six dial variants create specific strap colour considerations. Unlike the SKX007's all-black monochrome — which accepts any colour without contradiction — each Kamasu variant has its own colour logic.
Black dial, black bezel (RA-AA0001B): The most neutral Kamasu. Any strap colour works. Warm brown leather creates maximum contrast. Black rubber creates a unified dark combination.
Blue dial, blue bezel (RA-AA0002L): Cool maritime palette. Navy nylon creates tonal coherence. Brown rubber or leather creates warm-cool contrast.
Green dial, green bezel (RA-AA0003R): The most distinctive Kamasu. Olive or khaki nylon follows the green palette. Black rubber creates maximum contrast. Brown leather creates the most characterful combination.
Champagne dial, gold bezel (RA-AA0004E): The dress-sport variant. Brown or tan leather suits the warm gold hardware directly. Black leather creates formal contrast.
Black dial, blue bezel (RA-AA0005B): Cool bezel against dark dial. Navy nylon or blue rubber creates bezel-coherent tonal palette. Brown leather creates warm contrast.
Blue dial, black bezel (RA-AA0006L): Cool dial against dark bezel. Navy nylon for tonal coherence. Brown rubber or leather for warm contrast.
Best Rubber Straps for the Orient Kamasu
Orient produces its own OEM 22mm rubber strap for the Kamasu — the brand's own validation that rubber is the primary aftermarket material.
Tropical style FKM in black at 22mm watch straps — the most celebrated Kamasu rubber combination. The vintage basket-weave and honeycomb surface patterns reference the professional dive watch culture the Kamasu inhabits. Black tropical FKM on the black dial Kamasu creates a unified vintage combination with depth and texture.
Brown tropical FKM at 22mm watch straps — particularly effective on the green dial RA-AA0003R. Warm brown rubber against the green dial creates the most striking temperature contrast available on the Kamasu range.
Classic FKM rubber in black at 22mm watch straps — the most practical active upgrade.
Blue FKM rubber at 22mm watch straps — for the blue dial variants (RA-AA0002L, RA-AA0006L). Blue rubber on blue dial creates tonal coherence.
Green FKM rubber at 22mm watch straps — for the green dial RA-AA0003R. Green rubber on green dial creates a unified monochrome combination.
Best Nylon Straps for the Orient Kamasu
Single-pass nylon — Original at 22mm watch straps with the CNS solid buckle. Most appropriate Kamasu colourways by variant:
Black dial variants: Black, olive, navy, Admiralty Grey, black and grey.
Blue dial variants: Navy — for tonal coherence with the blue bezel. Black — for the most minimal combination.
Green dial variant: Olive — the most specifically coherent colour choice for the green dial. Khaki canvas for the most expedition character.
Marine Nationale elastic at 22mm watch straps — the most comfortable Kamasu daily wear option. Navy for the blue variants. Black for the black and green variants.
RAF single-pass nylon at 22mm watch straps — for the most specifically military heritage combination.
Canvas at 22mm watch straps in olive — suits the green and black dial Kamasu variants for a vintage expedition character.
Paratrooper elastic at 22mm watch straps — the most comfortable daily option.
Best Leather Straps for the Orient Kamasu
Leather on the Kamasu creates a compelling dress-sport transformation — the 200m diver becomes a versatile everyday piece. The champagne dial RA-AA0004E is particularly well suited to leather given its dress-adjacent character.
Leather watch straps in dark brown at 22mm watch straps — the most celebrated Kamasu leather combination across all dial variants. Warm brown against the cool brushed steel case creates a warm-cool contrast that is the most consistently rewarding Kamasu leather pairing. On the green dial variant, warm brown creates a bold temperature contrast — cool green dial, warm brown strap.
Leather watch straps in black at 22mm watch straps — the most formally correct combination. Particularly appropriate for the champagne dial RA-AA0004E in formal contexts.
Leather watch straps in tan suede at 22mm watch straps — the most relaxed leather option. Warm tan suits the champagne dial variant most naturally.
Leather watch straps in navy at 22mm watch straps — for the blue dial variants. Navy leather creates tonal coherence between strap and dial in a formal register.
