Designed for Compatibility

OCTAVIR Modular Watch Straps are independently designed aftermarket accessories engineered to fit a specific 40 mm bioceramic pocket watch case. Nine straps across two materials, two adapter variants, one precision-fit system. The watch is not included.

Two Adapter Variants

The target watch case comes in two crown configurations. To preserve a clean premium look, OCTAVIR produces two adapter variants — identical except for crown clearance position.

Variant L — Lépine

For case configurations with the crown at the 12 o'clock position. Single crown clearance cutout at the top of the adapter.

Variant S — Savonnette

Adapter-S · Crown @ 3

For case configurations with the crown at the 3 o'clock position. Single crown clearance cutout on the right side of the adapter.
