Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Bronze / Bronze / Leather Rubber

The lug width is 24mm. This refers to the distance between the two lugs where the strap attaches. Measure it correctly—from center to center of the lugs using a ruler positioned perpendicular to the case—to ensure complete compatibility with any 24mm strap available online or through specialist artisans.

The best choice depends on your usage. For formal elegance, a medium brown or cognac alligator strap complements a vintage blue dial beautifully. For daily versatility, a medium-weight calf leather (1.3–1.5mm) carries the 46mm case proportionally without excess weight. For aquatic environments, a NATO canvas strap or FKM rubber option offers practicality and durability. Your choice should respect both the dial colour and your lifestyle demands.

You will need a spring bar removal tool or a suitable substitute such as a small blade. Position the watch with the strap facing upward, insert the tool into the hole beside the lug pin, and gently compress the spring. Extract the old pin, then insert the new one and verify it is fully seated. Repeat on the opposite side. If uncertain, consult an expert to avoid scratching the case.

Any 24mm strap is compatible. Opt for one with a deployant clasp (folding buckle) or tang buckle, depending on your comfort preference. The deployant offers quick symmetric closure, ideal if you change straps frequently. Recommended materials include alligator, calf, shell cordovan, or robust canvas—all capable of supporting the weight and character of the case.

On a watch as large as the A1331233/Q616/295S/A20D.2 (46mm), the strap experiences considerable mechanical and thermal stress. A vegetable-tanned leather of quality typically lasts 18–24 months with daily wear. Duration extends to 3–4 years with sporadic use. Factors including humidity, sun exposure, skin transpiration, and maintenance (periodic conditioning) significantly influence longevity. Alligator or cordovan straps, being denser, can last 4–5 years with rotated use.
