Up for sale is the best homage build for the MM300.

Merkur Oceanmaster with the following mods.
HIMq ceramic insert (much more accurate and legible than merkurs)
Sharky endlinks (most accurate, the merkurs middle section stick out too much)
Longer clasp. Has more holes for better adjustment and fit.

Will come with the original clasp and all the links, plus the merkur rubber strap.

$350

Pics, time stamp and video (video really does this justice)
