Strap for Constellation Co-Axial 35 Stainless Steel / Yellow Gold / Diamond / Champagne

The lug width of the Omega Constellation 123.25.35.20.58.002 is 20 millimetres. This measurement is crucial for strap compatibility and ensures that the spring bar attachment between the lugs is proportioned to the case structure. All 20mm straps are compatible with this model.

For this two-tone case in yellow gold and steel, we recommend black or brown alligator for formal occasions, vegetable-tanned calf in cognac tones for daily versatility, or burgundy shell cordovan for elegance with character. Choose the material based on your usage: premium leather for formal events, structured rubber for dynamic wear.

Position the watch on a stable support and locate the lateral spring bar attachments beneath the case. Using a spring bar tool, gently press the lower attachment button and lift it to release the current strap. Repeat on both sides. Insert the new strap in the same manner, ensuring the attachments click into position with a crisp snap.

Yes, the Constellation 123.25.35.20.58.002 accepts any strap with a 20mm lug width. Artisanal straps in leather, rubber, or fabric offer customisable alternatives to the original bracelet. Verify that the width is consistent along the entire spring bar passage and that the attachments are stainless steel to prevent galvanic reactions with the two-tone case.

A premium leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years under daily use. Vegetable-tanned leather develops a natural patina, enhancing the perception of quality over time. With minimal maintenance – regular cleaning and drying after moisture exposure – durability is extended. The buckle and steel attachments remain intact indefinitely.
