Galactic A3733012/A717/213X/A16BA.1— lug 18mm

The Breitling Galactic 36 reference A3733012/A717/213X/A16BA.1 features an 18mm lug width. This measurement refers to the internal distance between the case lugs and is the essential parameter for selecting a compatible strap, whether an original Breitling piece or a bespoke aftermarket option.

For the Galactic 36, a vegetable-tanned alligator strap with a steel buckle or deployant clasp is the most coherent choice given the model's character. Smooth calf leather offers a versatile option for daily wear, whilst technical nylon NATO straps are well suited to more active use. All formats require an 18mm lug width.

To replace the strap, a springbar tool is required. Insert the pointed tip into the lug hole to compress the spring bar, then slide the strap outward. The process is fully reversible and does not require a watchmaker's intervention, provided it is carried out carefully to avoid scratching the case lugs.

Yes, any strap with an 18mm lug width is technically compatible with the Breitling Galactic 36. Milano Straps offers a selection of handcrafted straps in alligator, calf leather, shell cordovan and technical materials, all produced with curved ends designed to fit the lug geometry typical of Breitling cases.

The lifespan of a leather strap depends on material quality and frequency of use. A high-grade vegetable-tanned alligator strap can last between three and six years with ordinary care. Calf leather tends to show wear more readily, particularly in humid conditions. Avoiding prolonged water exposure and treating the leather periodically with suitable products will significantly extend the strap's life.
