Strap for Tonda Metrographe Stainless Steel / Black / Bracelet

The lug width of the Parmigiani Fleurier Tonda PFC274-0001401-B33002 is precisely 20mm. This width has been calculated in proportion to the 40mm diameter of the case and reflects classical Swiss design principles. The distance between the lugs must correspond exactly to 20mm to ensure compatibility.

The choice depends on the context of use. For formal occasions, we recommend alligator in havana or cognac brown tones, which maintains the aesthetic refinement of the watch. For daily use with natural patina development, vegetable-tanned calf leather in black or blue. For sport-elegant versatility, FKM rubber in grey or a woven cotton NATO strap. A stainless steel integrated deployante clasp offers micro-adjustable closure convenience whilst maintaining material coherence with the case.

The Tonda uses standard lug pins (double-ended bars). To change the strap: position the watch with the case facing upward, use a lug pin removal tool (usually supplied separately), gently extract the pin from the lugs, remove the old strap and insert the new one by aligning the holes with the lugs. Ensure the pin is fully inserted and that the strap is not twisted.

Yes, any strap with a 20mm lug width is mechanically compatible. However, to preserve the aesthetic integrity of the Tonda, we recommend selecting straps of equivalent quality: noble materials such as alligator, vegetable-tanned calf leather or FKM rubber. Avoid synthetic leather or budget materials that do not do justice to the refinement of the movement and dial.

A high-quality alligator or calf leather strap typically lasts 4-7 years with ordinary maintenance (monthly cleaning, protection from excessive humidity and heat). The precise duration depends on frequency of use, climate, sun exposure and the wearer's skin. Vegetable-tanned leather develops a natural patina that protects it over time. We recommend avoiding direct contact with salt water and allowing the strap to air-dry if wet.
