Strap for Galactic 36 Automatic Stainless Steel / Pearl / Bracelet

The Breitling Galactic A3733012/A788/376A has a lug width of 18mm. This measurement should be taken with a digital calliper or a millimetre ruler positioned between the two lugs at the point where they meet the case, perpendicular to the longitudinal axis of the watch. Any compatible aftermarket strap must have a precise width of 18mm at the attachment point.

For the Galactic A3733012/A788/376A, with its 36mm satin-finished stainless steel case, the most suitable straps are matte alligator for formal wear, vegetable-tanned calf leather for everyday use, or NATO and vulcanised rubber for sporting contexts. The ideal taper runs from 18mm at the lug to 16mm at the buckle, in order to respect the case proportions.

To replace the strap on the Galactic A3733012/A788/376A, you will need a fine-tipped or lever-style spring bar tool. Insert the tool into the slot of the spring bar between the lug and the strap, compress the spring, and slide the bar out. Exercise care to avoid scratching the stainless steel lugs. It is advisable to rest the watch face-down on a soft cloth during the procedure.

Yes. Any strap with an 18mm attachment is compatible with the Breitling Galactic A3733012/A788/376A, provided it uses standard spring bars. Milano Straps offers a selection of handcrafted 18mm straps — in leather, NATO, and rubber — designed to fit the Galactic lugs precisely without any structural modifications.

Longevity depends on the material and frequency of use. A vegetable-tanned calf leather strap, properly maintained, typically lasts 2 to 4 years with regular wear. Alligator, being denser and more compact, can exceed 5 years if kept away from water and excessive perspiration. Shell cordovan, owing to its dense fibrous structure, offers above-average longevity. Rotating between several straps significantly extends the life of each one.
