I’m searching for an 18mm bracelet to match with my c-cased, 70’s era, Ultra-Chron seen here: Must come with flat endlinks and be in the range of 16-17 cm (longer the better) when fully extended. Here is a picture of the too-short (for me) bracelet that came with my watch to give you an idea of the general look I’m going for:
I should clarify that I don’t necessarily need the bracket to be to be Longines-made... many 70’s era bracelets would work for me so long as it has flat endlinks.
