Strap for Constellation Manhattan 28 Quartz Stainless Steel / Yellow Gold / MOP

The lug width is exactly 19mm. This dimension derives from the compact 28mm case architecture with integrated lugs. Measured between the internal attachments, it must coincide precisely with 19mm to guarantee insertion without lateral play. Any compatible aftermarket strap must respect this tolerance.

For the 131.20.28.60.55.002 model with mother-of-pearl dial and two-tone yellow gold-steel case, we recommend black or dark chocolate alligator (vegetable tanning to develop golden patina), pearl grey smooth calf, or navy blue cotton NATO. Avoid pronounced textures or bright colours that would compete visually with the naturally luminous dial.

The 131.20.28.60.55.002 model features integrated non-removable lugs. The strap is inserted into the attachments through a manual procedure: position the new strap perpendicular to the case, align the lugs with the case lugs, and gently slide the strap until it locks. A delicate operation requiring precision to avoid scratching the yellow gold. We recommend entrusting the procedure to a specialist watchmaker.

Yes, provided the lug width is exactly 19mm. High-quality artisanal straps, custom-made in alligator, calf or rubber, are perfectly compatible. Always verify that the lugs have been constructed to precise tolerances to avoid friction on the case.

An alligator strap with vegetable tanning, used under normal conditions (non-extreme daily wear), lasts on average 3-5 years before showing visible wear. The Constellation's mother-of-pearl is not abrasive to leather. Longevity increases if the strap is kept away from direct sunlight and humid environments. The 18-month artisanal warranty covers manufacturing defects.
