Omega
Speedmaster (Non-Moonwatch) 321.30.44.52.01.002— lug 22mm

The Omega Speedmaster 321.30.44.52.01.002 has a lug width of 22mm. This dimension, measured between the inner shoulders of the case excluding the attachment screws, allows you to select specific straps without requiring structural modifications. On milanostraps.it you will find a dedicated collection of compatible straps in various materials and colorways.

The 321.30.44.52.01.002 suits multiple materials: Nile alligator for those seeking patina and contrast with the ceramic bezel; shell cordovan for construction density and natural aging; Tuscan vegetable tanning, ideal in brown or burnt orange tones, for vintage-racing pairings. Vulcanized rubber remains the lightweight option for saline or high-humidity environments.

The 22mm lugs on the 321.30.44.52.01.002 are typically secured with flathead screws. Use a precision tool (spring bar tool) to insert the tension spring into the lug hole: the new strap locks onto the screw and the lug returns to position. Ensure both shoulders are properly aligned with the case before wearing the watch.

Yes, provided the lug width is exactly 22mm. The artisanal straps from milanostraps.it are available in this size with customization options (length, color, stitching thread, deployant). The Casati Milano atelier also offers bespoke straps with personalized consultation.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) for the 321.30.44.52.01.002 has a durability of 3-5 years with regular maintenance: periodic cleaning, complete drying after humidity exposure, and rotation with other straps. Natural materials age rather than degrade, developing patina and character. Tuscan vegetable tanning is particularly long-lasting, especially in dry environments.
