The Omega Constellation Co-Axial reference 131.58.29.20.99.003 is housed in a round 18kt white gold case measuring 29mm in diameter and 10.6mm thick. A transparent case back offers a view of the automatic movement within, while scratch-resistant sapphire crystal protects the diamond dial above.
Water resistance to 50 metres keeps everyday wear well covered, and the watch arrives on an alligator/crocodile leather strap fastened with a tang buckle. The diamond bezel further elevates the piece, placing it firmly in the Constellation's diamond watch lineage.
This example is presented new and unworn, offered with reference 131.58.29.20.99.003 for precise identification.
