Uncle Straps Beads Of Rice. Seiko Marinemaster 300 SBDX001 Review

The only aftermarket Marine Master bracelet I'll ever approve, on a factory-fresh SBDX001

It's not a review of the watch, it's a review of what it's on. Mr Jun's SBDX001, the OG, the original and best Marine Master 300, bought from Daniel who kept it in its wrapper since 2011. Factory fresh, tags and all.

I hate aftermarket Marine Master straps. Me and Mr Jun have tried them all: Hexad, Engineer, Jubilee. But this Uncle Straps Beads of Rice, fitted with the OEM clasp, is the only one I've ever found that's actually good.

The verdict

I'm a purist and I love the original bracelet, but if you ever consider another one, this is the only one I can approve. £75 plus shipping, fits the whole SLA family, and on an SBDX001 this clean it's a marvellous marvellous twerp.

The line-up

Seiko SBDX001 Marinemaster 300

10/10 · Unreal scenario · Mr Jun's

The OG: double-domed Hardlex, lacquered bezel, monocoque case with zaratsu polishing, probably my favourite case, 025 excluded, and the old lume still holds up. Unreal scenario.

Uncle Straps Beads of Rice bracelet

8/10 · For the beeeech · Mr Jun's

Exceptional end link integration with less rattle than the OEM, links maybe a millimetre too thin, weird slots I quite like, and run it with the OEM clasp because theirs is no good.
