Lug width to be confirmed

On this Tudor Royal 28403-0003 the lug width doesn't convince me, and I don't want to give you a number I'm not sure about. Write to me on WhatsApp with the reference or a photo of the watch: I'll check it and tell you myself.

Frequently asked questions

What is the best strap material for the Tudor Royal 28403-0003?

For the two-tone 28403-0003, dark brown alligator with medium-fine grain is the classic choice, enhancing the warmth of yellow gold whilst creating contrast with steel. Alternatively, shell cordovan offers superior density and a natural patina that evolves over time, guaranteeing longevity beyond ten years. For those preferring vegetable-tanned leather, calf skin delivers progressive patina and sophisticated construction.

How do I change the strap on the Tudor Royal 28403-0003?

The Tudor Royal 28403-0003 uses standard Tudor Spring Bars. To change the strap: remove the watch from your wrist, locate the Spring Bars (small springs between case and strap), use the Spring Bar Tool to apply pressure and slide them out of the lugs, then insert the new strap by snapping the Spring Bar at the ends. Seek professional assistance if inexperienced, to avoid damage to the lugs.

How long does a leather strap last on the Tudor Royal 28403-0003?

Durability depends on material and usage: vegetable-tanned calf resists 5-7 years with routine maintenance; quality alligator 7-10 years; shell cordovan 10+ years. Exposure to perspiration, humidity fluctuations and direct sunlight accelerates ageing. The Casati Milano atelier provides an 18-month guarantee on all artisanal straps, with regeneration or replacement options available.
