got my seiko sumo, anyone know where to get bracelet or nato strap?
Think of getting mm300 rubber strap. good anot? ard 56usd
For aftermarket Sumo bracelets, you can try yobokies. Some popular models from yobokies include the Anvil, Hammer and Beads of Rice.
Alternatively, there are also suppliers, such as Strapcode, Tungchoy (not sure if it's the same as Strapcode) etc.
In my opinion, nato straps are best purchased online. Some popular retailers sworn by WUS forumers are TSS (The Strap Shop), Timefactors, Maratac, Westcoasttime, Holbens etc.
If you like to take a look and feel the strap in person, I think Gnomon Watches might be your best option. Do note that the natos / zulus sold thru different retailers are somewhat different in terms of quality. It may take some trial and error to find the one you like best. Thankfully they're cheap.
I have the Seiko MM300 rubber strap that came with the watch itself, but have never bothered to remove it from it's plastic cover to put it on. First of all, it does not look good to me, secondly, due to my small wrist, the length of the strap bothers me. Of course, YMMV.
