Strap for Tonda Metropolitaine Stainless Steel / Amarante / Diamond

The lug width of the Parmigiani Fleurier Tonda PFC273-0060900-HE242 is 18mm. This measurement is taken internally between the two lugs protruding from the case. A compatible strap must fit precisely to this dimension without play or resistance. Verify the measurement using a digital calliper positioned between the lugs: the result must be exactly 18mm.

For the Parmigiani Fleurier Tonda, we recommend an alligator strap with vegetable tanning, which combines formal elegance with durability. The alligator maintains its characteristic grain without competing with the case's simplicity, whilst vegetable tanning develops a natural patina over time. Alternatively, vegetable-tanned calf offers comfort and delicate texture. For more sport-oriented use, robust NATO straps in fabric guarantee practicality without sacrificing aesthetic integrity.

Remove the strap by extracting the spring bars using a dedicated tool (spring bar tool). Position the watch on a soft surface to prevent scratching. Insert the tool's tip beneath the spring bar, applying gentle pressure to compress the internal spring, then withdraw the bar towards you. Repeat on the other side. Insert the new strap by threading the bars into the lug slots and ensuring they click into position. Verify that the strap is perfectly aligned with the case.

Any strap with an 18mm lug width is compatible with the Parmigiani Fleurier Tonda PFC273-0060900-HE242. Milano Straps offers a comprehensive range of artisanal straps in alligator, vegetable-tanned calf, shell cordovan, NATO, and rubber—all constructed with the same precision regarding lug width. Before dispatch, each strap is verified to ensure perfect fit with the watch's spring bars.

The lifespan of a leather strap depends on material, usage, and maintenance. An alligator strap with vegetable tanning lasts approximately 5–7 years under moderate daily use. Vegetable-tanned calf has a slightly shorter lifespan, around 4–6 years, due to its more delicate texture. Constant exposure to moisture, perspiration, and sunlight accelerates deterioration. To extend strap longevity, keep it dry, avoid prolonged immersion, and occasionally apply a protective balm formulated specifically for vegetable-tanned leather.
