FAQ

What is the lug width of the Breitling Galactic A3733012/BD02/412X/A16BA.1?

The lug width of the Breitling Galactic A3733012/BD02/412X/A16BA.1 is 18mm. This is an atypical measurement by contemporary standards: it is essential to use only straps with a declared width of 18mm to ensure correct fit and safety.

What is the best strap for the Breitling Galactic 36 with 18mm lugs?

For the Breitling Galactic 36, the most suitable materials are vegetable-tanned alligator for formal occasions, shell cordovan for those seeking a natural patina that improves over time, and calf leather or rubber for sporting use. A steel buckle or deployant clasp at 16mm completes the system in keeping with the proportions of the 36mm case.

How do you change the strap on a Breitling Galactic A3733012/BD02/412X/A16BA.1?

Strap replacement is carried out using a fine-tipped spring bar tool: insert the tool into the spring bar slot inside the lug and compress the bar to release the strap. It is advisable to work on a soft surface to protect the case finishing. If in doubt, a watchmaker or the Casati Milano atelier can perform the operation without risk.

Are there aftermarket straps compatible with the Breitling Galactic 36?

Yes. Any strap with an 18mm lug width is technically compatible with the Breitling Galactic A3733012/BD02/412X/A16BA.1. Milanostraps.it offers a curated selection of handcrafted 18mm straps in various materials and finishes, all supplied with spring bars. For a bespoke result, the Casati Milano atelier produces made-to-measure straps with precise case fitting.

How long does a leather strap last on a Breitling Galactic 36?

The lifespan of a leather strap depends on the material, usage and care. A quality alligator strap, properly maintained with nourishing cream and kept away from prolonged exposure to water and perspiration, typically lasts between 3 and 5 years. Shell cordovan, owing to its compact fibre structure, offers superior durability. Casati Milano artisan straps carry an 18-month warranty against manufacturing defects.
