Strap for Galactic 36 Automatic Stainless Steel / Rose Gold / Volcano Black / Sahara

The lug width of the Breitling Galactic C3733012/BA54/213X/A16BA.1 is 18mm. This measurement should be taken with a digital calliper positioned between the two lugs at their innermost point, flush against the case. Respecting this exact dimension is essential to ensure a proper fit without placing undue stress on the lugs.

Given the two-tone rose gold and stainless steel case paired with a blue dial, the most suitable options are an alligator strap in navy or anthracite grey, a vegetable-tanned calf leather strap in tan to develop a natural patina over time, or a shell cordovan in burgundy for formal occasions. For everyday wear, a vulcanised rubber strap in 18mm preserves the leather options for more appropriate settings.

The strap is replaced by removing the spring bars that secure it to the case lugs. It is advisable to use a dedicated spring bar tool or fork-tip screwdriver to avoid scratching the two-tone case. If in doubt, a watchmaker or the Casati Milano atelier can perform the swap in a matter of minutes during an appointment.

Yes, any strap with an 18mm attachment is technically compatible. Milanostraps.it offers a curated selection of handcrafted 18mm straps in various materials — alligator, calf leather, shell cordovan, NATO and rubber — all finished to a standard befitting this Breitling reference's price point and aesthetic character.

Longevity depends on the material and conditions of use. A quality vegetable-tanned calf leather strap typically lasts between 2 and 4 years with regular wear, provided it is kept away from prolonged exposure to water and perspiration. Shell cordovan offers greater durability owing to its dense fibre structure. All Casati Milano straps carry an 18-month manufacturing defect warranty.
