Strap for Master Collection Date 38.5 Two Tone Rose / Roman

The lug width is 20 mm. This dimension is specific to this model and represents the optimal balance between the slender 38.50 mm case and visual proportion of the strap. To verify the measurement, measure the distance between the two lugs on the case interior, or consult the original documentation for the L2.628.5.19.7 reference (alternative reference L26285197).

The choice depends on intended use and aesthetic preference. For formal occasions, an alligator strap in burgundy or black satin enhances the case's classicism. A brown calf leather with vegetable tanning is ideal if you appreciate natural patina development. A grey ardoise canvas NATO offers daily lightness, whilst FKM rubber fully exploits the 300-meter water resistance, perfect for dynamic environments.

The procedure requires two tools: a spring bar tool and a stable work surface. Locate the two pins that pass through the case lugs at 12 and 6 o'clock: press with the tool to slightly retract the pin, then slide the original strap toward the edge of the case. Repeat symmetrically. Insert the new strap by aligning the two holes with the lugs, and press the pin until you hear the locking click. Verify the strap is securely fastened on both sides.

Yes, provided it is manufactured for 20 mm lug width.

Longevity depends on tanning method and usage. A calf leather with vegetable tanning, worn three to four days per week, lasts three to five years before lug repair is needed. An alligator with tannic aging easily surpasses ten years, developing a fascinating patina. FKM rubber, more resistant to humidity and UV rays, maintains elasticity for seven to eight years. In all cases, direct sunlight exposure and frequent perspiration reduce lifespan: rest between wearings is always recommended.
