Prospex Land SUN059P2— lug 24mm

The lug width of the SUN059P2 is 24 millimetres. This measurement must be verified by placing a caliper between the two internal lugs of the case. The 24mm specification requires dedicated straps—it cannot be adapted from standard 20mm or 22mm widths—to ensure proper fit and eliminate excessive play.

Selection depends on intended use: for formal occasions, an alligator strap with vegetable tanning or thickly-grained calf leather ages gracefully; for daily robustness, a black or stone-grey NATO strap; for field work, vulcanised rubber with textured grain. The choice should reflect this watch's tool-watch ethos, prioritising materials that develop character through continuous wear.

Remove the watch from your wrist. Using a non-abrasive instrument (spring bar tool or toothpick), gently lift the metal spring bar—the elastic keeper connecting strap to lug—from one side of the case. Once freed, remove the old strap. Thread the new strap through the spring bar, lower it into the opposite lug, and confirm the spring bar seats securely before rewearing the watch.

Certainly. Aftermarket straps designed for 24mm lug width are fully compatible with the SUN059P2, provided they meet that specification. Choose suppliers who certify measurement precision and offer quality deployant clasps (if desired over standard spring bars) for enhanced security.

A quality artisanal leather strap—whether alligator, calf, or shell cordovan—typically lasts 3–5 years with daily wear, depending on sun exposure, humidity, and care practices. The SUN059P2, being a heavy and frequently-worn instrument watch, accelerates natural wear. Gentle cleaning and prompt drying after water exposure significantly extends lifespan.
