Strap for Tourbograph Pour le Mérite Platinum / Silver

The lug width of the Tourbillon 702.025 is precisely 20 millimetres. This dimension is determined by the 41.20 mm case geometry and must be measured accurately between the two vertical lugs protruding from the case using a digital calliper. It is essential to use a specific 20mm strap, avoiding generic adaptations that could compromise fit and aesthetic harmony.

For the Tourbillon 702.025 in platinum, alligator represents the classic Saxonian choice due to its natural grain creating elegant contrast with the brushed metal. Shell cordovan is advised for those desiring longevity and a patina that evolves over time. Vegetable-tanned calf offers an organic texture that dialogues refinedly with the case. Avoid synthetic materials or suede: platinum deserves full-grain leather capable of ageing with dignity.

Strap changing requires a spring bar tool specific to watches. Insert the bifid tip of the tool inside the lug, press gently upwards to release the spring pin, and remove the strap. Position the new strap by aligning the holes with the pins and verify the closure is secure. If inexperienced, entrust the task to Casati Milano for professional service by appointment.

Yes, provided the lug width is exactly 20mm and the spring bars are the same size (standard 20mm × 1.2mm). MilanoStraps offers a dedicated collection of 20mm compatible straps crafted in artisanal leather. We recommend always verifying technical specifications and, for maximum assurance, using Casati Milano's services for personalised fitting.

A quality full-grain leather strap, worn regularly (5–7 days per week), has an average lifespan of 3–5 years before requiring replacement. Shell cordovan and alligator may last longer (5–7 years) due to leather's natural density. Longevity depends on wear frequency, climatic conditions and care (avoid excessive humidity and direct heat). Casati Milano provides straps with an 18-month warranty against manufacturing defects.
