Strap for Galactic 30 Blue / Diamond / Teju

The lug width of the Breitling Galactic A71340L2C814171Z is 20mm. This measurement is taken between the two lugs at the point where the strap attaches to the case — it does not correspond to the case diameter. Always verify this figure before purchasing any aftermarket strap.

For a 30mm stainless steel case, the most suitable materials are vegetable-tanned calfskin for everyday wear — supple, breathable and capable of developing a personal patina over time — and alligator leather in a narrow cut for formal occasions. A vulcanised rubber strap is the appropriate choice for sporting or marine use. A brushed steel buckle or deployant clasp ensures material consistency with the original case finishing.

Strap removal requires a spring bar tool: insert the tip into the lug slot, compress the spring bar and slide it free. Care must be taken to avoid scratching the polished case surfaces. Alternatively, a watchmaker or the Casati Milano atelier can perform the swap in minutes with no risk to the timepiece.

Yes. Any strap with a 20mm lug width is dimensionally compatible. It is also worth checking the strap thickness at the attachment end: on compact cases such as the Galactic 30mm, an overly thick strap can cause visual misalignment or interfere with caseback access. Milano Straps aftermarket straps listed for 20mm lugs are designed with proportions suited to this case size.

Longevity depends on the material and daily care. A quality vegetable-tanned calfskin strap, kept away from water and excessive perspiration and occasionally conditioned with leather cream, will typically last 2–4 years with regular use. Genuine alligator, due to the density of its scales, tends to last longer but requires the same attention to moisture. Milano Straps straps carry an 18-month warranty against manufacturing defects.
