I recently strayed off the Accutron reservation and bought an Omega Electromatic f300 Seamaster. The movement is a caliber 1260 and the watch is running strong and will soon be sent for full service/restoration. My question is the width of the lugs. My Accutrons use an 18mm band, and I fitted the Omega with a leather strap from my Accutron stash and it seems to be a wee bit small. Does the Electromatic require a 19mm or even 20mm band/strap? Thanks for any imput or clarification.
