Strap for Tonda 1950 Tourbillon Black Jade

The Tonda PFH279-1201400 has a lug width of 20mm. This measurement refers to the distance between the spring bars that connect the strap to the watch case lugs. To verify the correct measurement, position a ruler perpendicularly to the spring bar, from the centre of the upper spring bar to the centre of the lower spring bar. This dimension is essential when ordering compatible aftermarket straps.

For the Tonda PFH279-1201400, the most suitable straps are black or dark brown alligator, which creates formal elegance when paired with the white gold case. Alternatively, vegetable-tanned calf leather develops a unique patina over time, whilst shell cordovan offers extraordinary longevity. For sportier configurations, FKM rubber straps maintain the watch's formal character whilst offering wear resistance and water durability. NATO straps in natural silk are ideal for daily versatility.

To change the Tonda's strap, a specific tool is required: a spring bar tool or strap removal pliers. Position the tool under the spring bar, applying gentle pressure to compress the internal spring, then extract the bar from the case lugs. Insert the new strap, aligning it correctly, then re-insert the spring bar by compressing it again. For watches of this calibre, it is highly advisable to entrust the operation to an official service centre or specialised atelier.

Yes, any strap with a 20mm lug width is compatible with the Tonda PFH279-1201400. Milano Straps offers a complete range of 20mm straps in premium materials: alligator, vegetable-tanned calf, shell cordovan, FKM rubber and NATO. Compatibility is guaranteed by correct lug width measurement. It is advisable to verify the total strap length (from buckle to tip) to ensure wrist comfort.

The lifespan of a leather strap depends on the material and usage frequency. Premium-quality alligator offers 3-5 years of daily wear, vegetable-tanned calf reaches 2-4 years whilst developing a fascinating patina, whilst shell cordovan easily exceeds 5-7 years due to the natural stiffness and wear resistance of the leather. FKM rubber lasts over 7 years without significant aesthetic degradation. To extend longevity, it is advisable to rotate straps and apply conditioning treatments specific to the leather type.
