Strap for Navitimer Automatic 36 Stainless Steel - Red Gold / Grey / Bracelet

The lug width of the Breitling Navitimer U173271A1B1U1 is 18mm. This measurement is taken between the case lugs at the spring bar attachment point and is essential for selecting a compatible strap. On this 36mm model the dimension is fixed: a 17mm or 19mm strap will not fit the lugs correctly.

For the Navitimer U173271A1B1U1 in red gold and stainless steel, a vegetable-tanned alligator strap in tobacco or bordeaux tones is the most coherent aesthetic choice. Box calf leather suits daily wear, while a nylon NATO or technical rubber strap is well suited to sporting use and honours the watch's aviation heritage.

To replace the strap on the Navitimer 36, remove the spring bars connecting the strap to the case lugs using a fine-tipped spring bar tool, applying gentle leverage within the lug slot to avoid scratching the red gold case. Work on a soft surface and, if in doubt, entrust the operation to a qualified watchmaker or strap specialist.

Yes, numerous aftermarket straps are compatible with the Breitling Navitimer U173271A1B1U1. The essential parameter is the 18mm lug width. Milano Straps offers handcrafted straps in leather, alligator, shell cordovan, and technical materials, all supplied with spring bars included. It is also advisable to check the strap end curvature for an optimal fit against the original Breitling lugs.

The longevity of a leather strap depends on hide quality, maintenance, and frequency of use. A quality vegetable-tanned alligator strap, kept away from prolonged moisture and occasionally treated with a suitable leather conditioner, can last between three and six years with regular wear. Milano Straps leather straps carry an 18-month warranty against manufacturing defects.
