Strap for Constellation Quartz 35 Red Gold / White Supernova / Alligator

The lug width of the Constellation 123.53.35.60.52.001 is 20 millimetres. This specification is essential when purchasing a compatible strap: a strap that is too wide or too narrow would cause lug wear and difficulty when changing straps. To verify, use a digital calliper measuring at the point where the strap comes into contact with the spring bar.

For the Constellation 123.53.35.60.52.001 in rose gold, alligator remains the classic choice: its fine grain and natural patina pair perfectly with the warmth of the metal. Vegetable-tanned calf leather offers a more organic option and develops a personal patina over time. For those seeking practicality, rubber or NATO straps ensure full compatibility while maintaining visual balance.

To change the strap on a watch with 20mm lugs, first remove the spring bar using a dedicated tool: insert the tip into the small slot on the side of the lug and extract the spring bar with a gentle motion. Remove the old strap, check that the spring bar is intact, then insert the new strap ensuring the loop fully embraces the spring bar. Finally, reposition the spring bar in its original seat, verifying that it is completely seated.

Yes. Milano Straps offers 20mm straps in alligator, calf leather and shell cordovan specially coordinated for the Constellation. These compatible straps respect the proportions of the Omega case while preserving the minimalist character of the model. The Casati Milano atelier also creates completely bespoke custom straps, allowing you to choose leather, colour and finishes to match your watch.

A quality leather strap, such as alligator or vegetable-tanned calf, typically lasts between 3 and 5 years if worn daily. Durability depends on ambient humidity, sun exposure, frequency of wear and care. A shell cordovan strap, thanks to its natural rigidity and fibrous structure, tends to last longer. Milano Straps guarantees its straps for 18 months, covering manufacturing defects and premature wear.
