Strap for Tonda Metrographe Stainless Steel / Black / Bracelet

The lug width (ansa width) of the Parmigiani Fleurier Tonda PFC274-0001404-B33002 is 18 millimetres. This measurement corresponds to the distance between the two lateral lugs of the case and represents the fundamental parameter for selecting compatible watch straps. An 18mm strap will fit perfectly onto the Tonda's lugs, maintaining the original aesthetic proportions of the timepiece.

The best strap depends on intended use and personal preference. For formal and business contexts, we recommend an alligator strap in black or dark brown: the regular texture of the grains enhances the circular geometry of the case. For a more versatile approach, vegetable-tanned calf leather offers a natural patina that evolves with time, creating an emotional connection between timepiece and owner. For daily sports use, a NATO strap in canvas or recycled nylon provides practicality without aesthetic compromise.

Changing the strap on the Tonda requires the use of a spring bar tool (bayonet-style lug remover). Position the watch on a soft surface, carefully insert the flat end of the tool into the gap between the lug and the strap, and gently lift to disengage the spring bar. Repeat on the opposite lug. Ensure that the spring bars are correctly positioned in the new attachments before completing the installation.

Yes, all straps manufactured with an 18-millimetre lug width are compatible with the Parmigiani Fleurier Tonda PFC274-0001404-B33002. Milano Straps offers an extensive selection of artisanal 18mm straps in leather (alligator, calf, shell cordovan), fabrics (NATO), and rubber, customisable according to the aesthetic and functional requirements of each owner.

The lifespan of a leather strap depends on material quality, daily use, and environmental conditions. A high-quality alligator or calf strap, subjected to regular use and proper maintenance (occasional cleaning, protection from standing water), has an average life of 5–8 years. A shell cordovan strap can exceed 10 years. Vegetable tanning develops a denser patina over time, visually extending the life of the accessory. To extend durability, we recommend avoiding prolonged water immersion and rotating straps if you own the watch with multiple accessories.
