I've just order a US flat link bracelet (speedmaster). Think will take a couple of weeks to arrive to the UK. Will post back whether it fits the Helson Sharkmaster 300 or not.

Nice pics! I've got mine recently. Agreed, it is indeed a hell of a watch! Definitely 1 or 2 (or more) levels above the other homage watches that I've owned in the past. It reminds you of that famous design but with its own twist added to the mix!

What is the mesh bracelet you've got on there? Staib?

Just got the same model myself, love it! The lume is surprisingly strong I must say. The spring-bar connected bracelet is a bit odd, and I feel that the clasp lets the watch down somewhat.
