This strap was designed for the Marine Master and looks exactly right. This Seiko strap is exactly as good, and as stiff, as they are known to be. This is not a strap one gets for great comfort, as it is stiff, nor for long life: the stiff straps will crack and fail long before a softer rubber or silicone dive strap will. This is a strap one gets to put on a watch that either originally came with it, or that looks just like an older Marine Master.

Bought this for my new MM300 as the newer version rubber waffle strap with SS strap holder, whilst pretty, is just a scratch magnet. Asking price was also very good.

It’s almost a must for the Marinemaster 300m. If you want to be period correct, no other strap works. It’s a great strap, comfortable and unique on your 300m.

Great strap, looks awesome, super stiff / hard but it’s comfortable so I guess it doesn’t matter.
