Why will no strap fit my watch?
Because there is probably nothing to measure. On an integrated bracelet the case has no lug width.
watches in the database are built with an integrated bracelet, 6.1% of 42,813 references. Measured 2026-08-27.
What an integrated bracelet is
On a conventional watch the band sits in a gap between two lugs, held by a spring bar, and any band of the right width fits. On an integrated design the bracelet is drawn as part of the case: the first link continues the case profile, the shape of the opening belongs to that model alone, and often there is no straight gap at all.
That is why a band bought by size will not go in, or goes in and sits wrong. The size was never the problem.

What fits instead
A band cut to that specific case. The end of the band is shaped to follow the case profile, so it closes the opening the way the bracelet did. It is made to the watch, measured on the watch, and no catalogue size substitutes for it.
