Strap for Jules Audemars 26344 Grande Sonnerie Carillon Platinum / The Hour Glass Black

The lug width of the Jules Audemars ref. 26344PT.OO.D002CR.02 is 18 mm. This is the internal distance between the lugs of the case, measured with a millimeter caliper directly on the watch to avoid errors before ordering a replacement strap.

For a 950 platinum case with Grande Sonnerie, an alligator strap—either polished glossy or matte opaque—is the choice most consistent with the formal register of the watch. Box-calf leather is a valid alternative for daily wear, capable of developing a personal patina over time. Avoid NATO and rubber, which are unsuitable for this reference.

The strap is removed using a dedicated springbar tool with a fine tip, inserting the tip into the seat of the spring bar present on the lug. Compress the spring bar, slide the strap outward, and repeat on the other side. Installation of the new strap is done in reverse. On a platinum watch of this value, it is recommended to entrust the operation to a watchmaker or authorized retailer to avoid scratching the case.

Yes. Any strap with an 18 mm attachment is technically compatible with this reference. Milano Straps offers a selection of artisanal 18 mm straps in various materials and finishes, designed to suit the proportions of formal wristwatches such as the Jules Audemars. The Casati Milano atelier also produces bespoke straps made to measure.

The durability of a leather strap depends on the quality of the material, care, and use. A high-quality alligator or calf leather, kept away from water, excessive perspiration, and direct light, maintains its aesthetic and structural qualities for two to four years with regular use. Milano Straps offers an 18-month warranty on manufacturing defects. Periodic strap replacement is an integral part of fine watch maintenance.
