Strap for P3/03 Bully

The SevenFriday P3/03 features a lug width of 28mm. This measurement is taken from the inner edge of the left spring bar to the inner edge of the right spring bar using a digital calliper. The 28mm dimension is a versatile standard that accommodates substantial artisanal straps, perfect for complementing the proportions of the 47mm case.

Vegetable-tanned alligator represents the most sophisticated choice: its natural grain contrasts elegantly with the case's industrial aesthetic. For versatility, black vitello with vegetable tanning delivers impeccable visual clarity. NATO cordura straps provide sportive functionality, whilst structured rubber in monochromatic black creates refined coherence ideal for professional environments.

Remove the watch from your wrist and locate the horizontal spring bars passing through the lugs. Using a spring bar tool, apply gentle upward pressure to the left bar to release it from its seat. Repeat on the right side. Position the new strap by aligning the spring bars with the lug holes, then press firmly until you hear a click. Verify both bars are fully seated before wearing.

Any strap with a 28mm lug width is compatible. Milano Straps offers a complete collection of artisanal leathers: alligatore, vegetable-tanned calf, shell cordovan, cordura NATO, and marine-grade rubbers. Every strap is made-to-order with customisation options in colour, stitching thread, and closure type—buckle, deployant clasp, or pin.

A strap crafted from vegetable-tanned leather, with regular maintenance (monthly cleaning with a damp cloth, quarterly conditioning with vegetable wax), retains structural integrity for 3–5 years of daily wear. The patina developing over time represents an aesthetic asset, not a defect. Structured rubber and cordura NATO straps exceed 5–7 years without significant deterioration, thanks to the material's inherent durability.
