Unfortunately no, I sold the original bracelet from my 031 because I didn't like it.Do you still have both to do a comparison? I've owned recent Seiko bracelets in the form of the SLA021 and the 775 Turtle (at different ends of the spectrum) the general standard is improving but most still fall miles short Strapcode or Micros.
I actually quite like the MM300 bracelet but on dressier divers and wish the Tuna kept its more rugged look!
The clasp especially was very tinny.
On the new version I have the bracelet seems the same. However, to me, the clasp feels a lot more secure. Maybe not strapcode secure, which I also have, but certainly very much improved.
