Ref. L390/03635
The Corum Big Bubble Magical 52 Titanium / Nelson de la Nuez / Rubber takes a 26 mm strap: measure between the lugs and that is the only number you need. We list 15 straps in that width. With a 52 mm case and 100 m of water resistance, a thicker strap balances the case. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
We do not sell watches. This page exists to find the straps that fit this one.
