Strap for Tourbillon Minute Repeater Perpetual Calendar 5307

The lug width of the 5307P-001 is precisely 18 mm. This measurement represents the vertical distance between the two case lugs and corresponds to the strap width to be used. It is important not to confuse this dimension with the case diameter (41 mm). To measure correctly, use a digital calliper positioned on the inner shoulders of the spring bars.

Alligator represents the most coherent choice with the positioning of the 5307P-001. The natural texture of the scales evolves over time in harmony with the ageing of platinum. Shell cordovan constitutes an excellent alternative for those seeking a leather that develops deep patina over the years. Vegetable-tanned calf offers a compromise for those who prefer initially soft leather destined to acquire chromatic character over time.

Changing the strap of the 5307P-001 requires the use of a spring bar tool (specialised pin extractor) to remove the spring bars from the two case lugs. This operation is recommended to be performed by a qualified watchmaker to avoid scratches on the platinum case. Casati Milano offers a complete strap change service with personalised WhatsApp assistance.

An aftermarket strap for the 5307P-001 must have an 18 mm lug width, well-crafted lugs and a thickness proportionate to the prestige of the platinum case. On milanostraps.it you can discover a selection of artisanal 18 mm straps made in alligator, shell cordovan and calf, all constructed according to haute couture standards and compatible with the model.

The lifespan of a leather strap depends on the material and daily wear. High-quality alligator with vegetable tanning can last 5-7 years under normal use conditions. Shell cordovan, if properly maintained, can exceed 10 years while developing increasingly pronounced patina. Calf has an average lifespan of 3-5 years. All Casati Milano straps benefit from an 18-month warranty on manufacturing defects.
