For the 511.OX.0500.VR.BER16 with Berluti dial, the best pairing is an alligator strap with Louisiana grain texture, preferably in black or cognac. The texture of the premium leather complements the hand-crafted Venice dial, while a rose gold deployant clasp echoes the King Gold of the case.

How do you change the strap on the Hublot Classic Fusion 511.OX.0500.VR.BER16?

The strap is removed using a dedicated springbar tool with a fine tip inserted into the lug seat, compressing the ends of the spring bar to release it.
