Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Yellow Gold - Diamond / Green Meteorite

The Omega Constellation 131.55.29.20.99.005 has a lug width of 18mm, measured center-to-center of the lugs. This specific dimension requires straps built with millimeter precision to ensure stability and wearing comfort.

Vegetable-tanned alligator represents the ideal choice: the natural grain does not compete visually with yellow gold but enhances it, and the natural patina that develops over time creates a unique aesthetic complementarity. Vegetable-tanned calf with natural aging is a valid alternative for those who prefer more pronounced textures.

Use a quality artisanal spring bar tool. Remove the original bracelet by gently pushing the spring bars from inside toward outside. Verify that the new strap has lugs of the same width (18mm) and reinsert the spring bars with precise and slow movements. If you lack experience, entrust the task to a specialized watchmaker.

Yes, provided the artisanal strap is built for 18mm lug width. Aftermarket straps of quality made in alligator or calf with artisanal deployante clasp maintain the constructive coherence of the watch and allow personalization impossible with the original bracelet.

A high-quality alligator or calf strap with vegetable tanning lasts on average 4-6 years with daily wear, provided periodic maintenance (cleaning, drying after moisture exposure). The patina that develops is part of the artisanal beauty, not a defect. Premature deterioration indicates inferior materials or industrial tanning.
