Strap for Galactic Chronograph II Stainless Steel / Blue

The Breitling Galactic A1336410/C645/105X has a lug width of 20mm. This measurement refers to the internal distance between the two lugs and determines the compatible strap width at the attachment point. Before purchasing a replacement strap, it is advisable to confirm the measurement using a digital calliper directly on the case.

For the Galactic 44mm, the most suitable materials are matte alligator leather for formal occasions, vegetable-tanned calf leather for everyday wear, and vulcanised rubber for sport or humid environments. A tapered strap from 20mm to 18mm provides the most coherent visual continuity with the case geometry. A steel deployant clasp is the closing mechanism most consistent with the technical character of this model.

Strap replacement requires a spring bar tool — a forked instrument that compresses the spring bars housed in the lug holes. Insert the tip of the tool between the strap and the lug, compress the spring bar, and slide out the strap. The operation should be carried out carefully to avoid scratching the stainless steel case. If in doubt, it is advisable to entrust the task to a watchmaker or the Casati Milano atelier.

Yes: any strap with a 20mm attachment width is technically compatible with the Breitling Galactic A1336410/C645/105X. milanostraps.it offers a selection of artisan aftermarket straps — in alligator, calf, shell cordovan, NATO, and rubber — made to a standard 20mm width and available with customisable lengths and buckles. It is important to select straps with spring bars included or compatible with the diameter of the original Breitling lug holes.

The lifespan of a leather strap depends on the material, frequency of use, and exposure to perspiration and humidity. A quality vegetable-tanned calf strap lasts on average 2–4 years with daily wear; alligator leather, due to its fibre density, can exceed 5 years with proper care. Shell cordovan offers the highest resistance to abrasion. All Casati Milano straps are covered by an 18-month guarantee against manufacturing defects.
