Choisir sa montre Omega en trois temps
1. Define the use
Case diameter, movement type (automatic or quartz) and daily wear or occasional use: three questions to answer before choosing the model.
2. Decide on the material
Steel for versatility and liquidity, gold for intrinsic value, titanium for lightness. The original strap contributes to the value.
3. Verify before buying
Each watch Omega we list is appraised in Paris (Entrupy assisted analysis followed by manual review), delivered with a certificate, an invoice and 10 to 14 days of insured shipping.

How to authenticate
- Case and movement numbers consistent with each other and with the reference
- Calibre opened in workshop: original finishes, engravings and parts
- Original dial and hands, homogeneous lume, no repainting
- Strap, deployant buckle and links stamped by the manufacturer
