The Museum Collection 516.52.48.30.04.001 (aka: 51652483004001), seen from the bench

The Omega Museum Collection 516.52.48.30.04.001 is a 47.50 mm chronograph combining white gold and Sedna gold (Omega's proprietary 95.65% rose gold alloy) with an artistic cloisonné enamel dial. The case features a 20 mm lug width and houses the Omega caliber 3018, a column wheel chronograph with co-axial escapement developed in the 1940s. This timepiece balances substantial proportions with refined proportions, offering hours, minutes, small seconds and chronographic function in a sculptural expression of Swiss watchmaking craftsmanship.

Frequently asked questions

What is the lug width of the Omega Museum Collection 516.52.48.30.04.001?

The lug width is 20 mm. This width is standard for Omega Museum Collection chronographs and is essential to ensure stable attachment and play-free fit between the lugs and the strap.

Which strap do you recommend for the Museum Collection 516.52.48.30.04.001?

To enhance the chromatic dialogue between white gold and Sedna gold, we recommend dark alligator (tan brown), vegetable-tanned calf in tobacco tone, or shell cordovan for tactile density. A silk NATO strap for those seeking contemporary practicality while maintaining elegance.

How do you change the strap on the Museum Collection 516.52.48.30.04.001?

Position the watch on a soft surface, locate the spring bar release pin with a dedicated tool, push the pin toward the opposite side to free one end, remove the old strap, insert the new one by aligning the holes and release the pin. An operation requiring care to avoid scratching the white gold.

Are the compatible straps available online certified by Omega?

No, they are superior quality artisanal aftermarket straps. 100% compatible with the 20mm lug width, they allow customization in leather, thread color and length. Certified 18-month warranty at Casati Milano.

How long does a leather strap last on a chronograph like the 516.52.48.30.04.001?

A superior quality alligator or calf strap lasts 5-7 years with regular use. The patina develops positively. With vegetable tanning, the leather ages gracefully. Natural rubber lasts 3-4 years. Durability depends on maintenance (humidity and heat exposure) and frequency of use.
