Strap for Pilot Automatic Black / Calf

The lug width of the Formex Pilot 1100.1.7020.223 is 22mm. This measurement indicates the distance between the two lugs that anchor the strap to the case. It is essential to ensure that the strap you choose is compatible with this specific measurement to guarantee a secure fit without lateral play.

For the Formex Pilot 1100.1.7020.223, we recommend vegetable-tanned Tuscan leather in tobacco or honey brown tones, or genuine alligator for those seeking ultimate discretion in luxury. For more operational contexts, a heavy canvas NATO strap or vulcanised rubber strap provides water resistance and practicality. Your choice depends on your actual use of the instrument.

To change the strap, you must remove the spring bars that anchor the current strap to the case. Use a dedicated spring bar tool to gently press and slide the bar downward. Insert the new strap into the lug holes and snap the spring bars back into position. Verify that the strap is firmly seated before wearing the watch.

Yes, you can use quality aftermarket straps of 22mm lug width. Ensure that the strap is explicitly compatible with 22mm width and that the internal lug openings are correctly calibrated. A high-quality artisanal strap often provides superior fit and aesthetic ageing compared to generic straps.

The lifespan of a leather strap depends on material quality and usage. A high-quality vegetable-tanned leather strap, worn daily, has an average useful life of 2–4 years before requiring replacement. However, with proper maintenance (periodic cleaning, complete drying after water exposure) and rotation with other straps, longevity can extend. Shell cordovan leather is more durable and may last 4–6 years.
