Strap for Uni-Racer Safari

The Massena LAB Uni-Racer UR-001-SAF features a lug width of 20 millimetres. This dimension is compatible with all straps in Milan Straps' 20mm collection. For maximum precision, we recommend measuring the internal space between the lugs with a digital calliper: manufacturing tolerance is typically ±0.2mm. The recommended strap thickness must not exceed 4.5 millimetres to maintain the visual balance of the case.

For this reference we recommend an alligator with vegetable tanning or a calf leather with vintage finish. Alligator emphasises the case geometry through its natural grain and creates contrast with the dial. Calf leather, with vegetable tanning, develops a fascinating patina over time, transforming the chronograph's appearance after a few months of use. Both options maintain aesthetic coherence with the spirit of the Uni-Racer, conferring elegance without excess.

Strap replacement is a straightforward operation requiring no specialised tools. Flip the watch over and examine the two lugs holding the strap in place. Using a dedicated tool (spring bar tool) or, with care, the tip of a small knife, gently press on one of the two spring bars from the lugs: the spring-loaded pin retracts and the old strap extracts easily. Insert the new strap by aligning the holes with the lugs and apply gentle pressure until you feel the click of closure. Verify that the strap is firmly fixed by gently pulling in opposite directions.

Yes, the Massena LAB Uni-Racer UR-001-SAF is fully compatible with high-quality NATO straps. A NATO in technical nylon with 20mm width transforms the chronograph's aesthetic towards a more informal and sporty interpretation, ideal for daily activities or less formal settings. The dual-lug configuration ensures safety even during dynamic activities. We recommend choosing a NATO with texture or weave that creates contrast with the dial, avoiding visual monotony.

The lifespan of a leather strap depends on usage intensity and care. A high-quality alligator or vegetable-tanned calf lasts approximately 3-5 years with daily use, up to 7-10 years with occasional wear. The leather wears gradually through contact with the wrist and the environment; the patina that forms is synonymous with character and authenticity. To extend lifespan, we recommend rotating the watch across different straps and protecting the leather from excess moisture. An FKM rubber strap maintains its properties intact for 5-8 years, with gradual degradation of flexibility after this period.
