Datejust 36 116233-0191— lug 20mm

T he lug width is precisely 20mm. This is the measurable distance between the two pins that secure the strap to the watch lugs. Accurate measurement ensures the strap seats flush with the case flanks without radial play. Use a digital calliper, measuring perpendicular to the watch face between the horizontal pin protrusions. Correct fit is essential for both aesthetic alignment and structural integrity of the strap-case interface.

T he optimal choice depends on context and aesthetic sensitivity. Alligator leather finished with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> offers exceptional visual texture and patina development, ideal for formal occasions and evening wear. Swiss or Italian calf leather provides softness and daily comfort. <a href="/pages/termine-glossario/shell-cordovan">Shell cordovan</a> develops a distinctive iridescent patina through organic ageing, revealing depth invisible in new leather. NATO and rubber straps deliver sports-functional durability. Casati Milano creates bespoke straps where leather selection occurs in the Milan atelier, observing your chromatic sensitivity and use case. The bicolour Datejust demands materials that harmonise yellow gold with stainless steel without chromatic discord.
