Strap for PrimaLuna Automatic 30 Stainless Steel / Blue MOP / Bracelet

The lug width is 8mm, a rare and precise specification. We recommend measuring using a digital calliper positioned perpendicularly to the watch's axis, measuring the internal dimension between the metal lugs. A precision of ±0.5mm is essential to avoid incompatible straps.

Alligator represents the ideal formal choice thanks to its scale texture that echoes the dial's guilloché pattern. Vegetable-tanned calf leather offers an informal yet elegant character and develops patina over time. For daily versatility, a saffiano NATO in neutral tones ensures practical changeover. Shell cordovan is not recommended: its initial stiffness conflicts with the delicate proportions of this 30mm case.

Obtain a spring bar removal tool or consult a watchmaker. Support the lug gently with the tool in the small groove at the side of the spring bar, applying controlled pressure to avoid scratching the stainless steel case. Once freed, extract the old strap and insert the new one, ensuring the spring bar seats firmly in the lugs. Verify that the strap edges adhere perfectly to the case.

Yes, any strap with an 8mm lug width is physically compatible. We recommend choosing specialized manufacturers who pay attention to proportions and finishing: poorly executed or coarse straps will compromise the PrimaLuna's aesthetics. Milano Straps offers a selection of premium 8mm straps, customisable in length, colour and buckle.

A high-quality alligator or calf leather strap, subject to regular maintenance (periodic cleaning, protection from excessive moisture), maintains structural integrity for 5-8 years of daily use. The leather gradually thins and fibres fatigue—a signal to consider replacement. Dry climates and occasional use extend lifespan to 10 years. Milano Straps guarantees its straps for 18 months.
