Strap for Royal Date 28 Stainless Steel - Yellow Gold - Diamond / MOP

The lug width of the Tudor Royal 28323-0001 is 20 millimetres. This constructive specification is critical when selecting the correct strap: lug width, also termed ansa measurement, is the distance between the two spring bar fixing points on the case. To verify compatibility, measure the external distance between the insertion points: the value must be exactly 20mm. A strap of incorrect width will not secure properly and risks scratching the case during installation.

For the Tudor Royal 28323-0001, alligator leather is the solution of absolute excellence: regular granular texture and fine grain enhance the bi-metal sophistication of the case. Alligator in burgundy or dark brown amplifies the presence of yellow gold, creating an elegant chromatic dialogue. An established alternative is calf leather, available in cognac or black, which offers uniform grain and daily versatility. For sports-oriented solutions, textile NATO in jacquard or cotton-silk maintains the dignity of the case with greater casualness.

To change the strap on the 28323-0001, extract the spring bars using a dedicated spring bar remover tool, a palette instrument inserted between case and lug. Position the palette in the spring bar groove and apply gentle outward pressure to release the spring. Once disengaged, the strap detaches from the case. For installation, align the new strap's holes with the fixing points and reinsert the spring bars until they click into place. Verify that the strap is centred on the case with no irregular gaps.

Yes, the Tudor Royal 28323-0001 accepts quality aftermarket straps, provided they respect the 20-millimetre lug width specification. Aftermarket and artisanal straps offer superior material range, colourways and customisation compared to original Tudor straps. Specialised manufacturers produce alligator, calf, shell cordovan and FKM rubber specifically calibrated for 20mm lugs. Compatibility is guaranteed by width conformance: always verify that the new strap is explicitly manufactured for 20mm lug width.

The lifespan of a leather strap for the 28323-0001 depends on material quality, daily wear patterns and maintenance care. An artisanal alligator or calf of quality, worn daily, lasts on average between 3 and 5 years. Alligator tends to age better, developing natural patina that increases aesthetic appeal. Calf, softer to the touch, may show visible edge wear after 2–3 years of intensive use. To extend longevity, avoid prolonged humidity exposure and alternate straps with others, allowing the leather to rest and dry thoroughly.
