Hello, i want to order a clasp and leather strap for my Speedmaster and try to find out the sizing of the genuine leather strap and clasp size of the Speedmaster with leather strap (311.33.42.30.01.002). From my findings i get following: 1) Leather strap 20mm lugs / clasp 16mm 2) Leather strap 20mm lugs / clasp 18mm Could anyone please confirm which of those two matches the original strap and clasp size of the above watch reference? Thank you
Both 20mms fit that ref. But I don't see the taper being mentioned at the omega site. The ref you provided is for the display back version, while 311.33.42.30.01.001 is the solid back version. So just choose which taper you like.
personal preference, i would go for the 20mm/18mm. the 16mm is too narrow for my taste edit: search is your friend https://omegaforums.net/threads/help-with-straps.32974/
The 20mm / 18 mm appears to be more common and has more wrist presence than the 16 mm. I've got both variants and prefer the 18 mm.
311.33.42.30.01.001 and 311.33.42.30.01.002 come with the same strap.I know that i could choose between the 18mm and 16mm clasp. My question is with what clasp size the original leather strap of the watch comes with. 16 or 18mm ? Thank you
