Strap for Constellation Quartz 27 Polished Red Gold / Snow / Diamond Supernova

The lug width is exactly 18 millimetres. This measurement represents the distance between the two case lugs where the strap connects. It is essential to measure it correctly by positioning a digital calliper perpendicularly between the lugs to ensure compatibility with aftermarket straps.

For the 27mm format in red gold, alligator in cognac or tobacco brown tones creates the most elegant aesthetic harmony thanks to its chromatic affinity with the case. Black calf is ideal for formal occasions, while natural or synthetic rubber represents the best choice for those pursuing an active lifestyle without compromising refined aesthetics.

Strap replacement is performed by removing the two spring bars that connect the strap to the case. You must use a spring bar tool or a dedicated instrument to press the ends of the bar and extract it from the lug holes. After removing the old strap, insert the new one by snapping the spring bars into the corresponding seats on the case. If you are unsure about the procedure, a jeweller or a specialized workshop can perform the operation in just a few minutes.

Yes, it is completely possible. Any strap with an 18mm lug width is compatible with your watch. Milano Straps offers a collection of 18mm straps made from premium materials such as alligator, calf, shell cordovan and rubber, customizable with initials, choice of thread colour and length adapted to your wrist.

Durability depends on the material and usage. A quality alligator strap, subject to moderate daily use, can last 3-5 years before showing visible signs of wear. Calf tends to wear slightly faster (2-4 years), while shell cordovan can exceed 5-7 years if properly maintained. Natural rubber has durability comparable to calf. The 18-month warranty offered by Casati Milano covers any manufacturing defects; wear is instead considered normal consumption.
