Strap for Royal Date 34 Stainless Steel / Silver - Diamond

The Tudor Royal 28400-0002 features a lug width of 20 millimetres. This measurement represents the distance between the case attachment lugs and determines strap compatibility. To verify with precision, position a ruler perpendicular to the dial, measuring the distance from inside to inside of the metal pins: the result will invariably be 20mm for this model.

Alligator represents the narrative choice par excellence: the natural scale texture harmonises with the fluted bezel, and the patina developed over time amplifies the vintage-inspired character. For those preferring contemporary rigour, shell cordovan offers superior compactness and durability. Vegetable-tanned calf leather embodies the ideal compromise between initial flexibility and elegant ageing. For informal versatility, textile NATO straps in neutral tones permit rapid variation without multiple investments.

The Tudor 28400-0002 uses removable spring bars. Obtain a dedicated tool (spring bar pin remover) or a very fine pointed instrument. Position the watch with the strap facing upwards, locate the small hole beneath the pins, insert the tool applying gentle pressure to push the pin inward, then extract the pin from the case. Repeat on the opposite side. Insert the new strap by aligning the holes with the case attachments, then reintroduce the pins until the mechanical click that guarantees secure anchoring.

Yes, aftermarket straps are fully compatible if the lug width is 20 millimetres. Milanostraps.it offers artisanal straps available in this dimension, with personalisation options: leather choice (alligator, calf, shell cordovan), colour, thread type, and buckle finish. The Casati Milano atelier additionally creates bespoke straps by appointment, with the possibility of personally selecting leathers and receiving updates during realisation.

Durability depends on the leather type and usage patterns. A well-maintained alligator strap lasts 5–7 years of daily wear, developing a desirable patina. Shell cordovan, being more compact, can exceed 10 years. Vegetable-tanned calf leather has an average lifespan of 4–6 years. Conditions that shorten longevity include prolonged humidity exposure (rain, perspiration), direct sunlight, and extreme temperatures. Simple maintenance—monthly cleaning with a soft cloth, annual treatment with a balsam specific to artisanal leathers—significantly extends durability.
