Strap for D-Star Automatic White

The lug width of the Rado Oval R15964012 measures 18 millimetres. This specification refers to the internal distance between the two lugs of the case where the strap is inserted. For precise verification, we recommend measuring internally from lug to lug using a digital calliper after removing the original strap. This specification permits the use of any artisanal strap manufactured for 18mm lugs, ensuring universal compatibility.

For the Rado Oval R15964012, we recommend straps in alligator with vegetable tanning (fine grain) or polished calf leather for formal occasions, as they enhance the luxurious character of the ceramic case. For more elegant sporting use, a NATO strap in cotton canvas or a moulded FKM rubber reflects the modernist heritage of the model. Shell cordovan represents a refined intermediate solution with natural patina that develops over time.

Strap replacement is performed using standard 18mm spring bars. Obtain a dedicated tool (spring bar tool) that permits gentle compression of the bar and disengagement from the lug seat. Insert the flat end of the tool into the lower recess of the spring bar, apply gentle pressure until disengagement, then extract the bar. Repeat the operation on the other lug. For installation of the new strap, align the holes with the spring bars and press until complete insertion into the seats, verifying attachment with gentle tension.

Yes, all artisanal straps manufactured for 18mm lugs are fully compatible with the Rado Oval R15964012, provided they feature standard spring bars. We recommend verifying that the strap presents appropriate thickness (typically 3.5-4mm at the lugs) and that the spring bar insertion holes are perfectly aligned. Artisanal straps realised bespoke by specialist ateliers guarantee superior construction quality to serially manufactured alternatives.

A quality leather strap (alligator, calf, shell cordovan) for the Rado Oval R15964012 maintains structural integrity for 3-5 years with moderate daily wear and regular maintenance. Extension of lifespan depends on: frequency of wear, ambient humidity, protection from direct sunlight and periodic maintenance (cleaning with damp cloth and conditioning with leather-specific creams). Vegetable tanning tends to develop natural patina over time, enhancing aesthetics. FKM rubber straps offer superior durability (7-10 years) with minimal maintenance.
