Available adjustment is 2.3 mm. Start @ 17:00

The new bracelet is so slinky and has such small links, my opinion is 2.3mm will work.

The SM300MC and 300m have the multi position microadjust clasp. They are heavier watch heads and the bracelet links are larger.

The more microadjust the better though.

Concur.

15.89 is the actual outside measurement IIRC. 15mm is the inside of the clasp

The 2012-2017 SMPc bracelet w/1154 toolless microadjust clasp added made a believer out of me. Fit is everything IMO.

THANKS all for the info here.

My uneducated guess is there will be a direct fit part forthcoming.
