Strap for Day-Date 40 Yellow Gold / Green - Roman

The lug width of the Rolex Day-Date 40 228238-0061 is precisely 20.00 millimetres. This dimension is standard for the model and critical when selecting an aftermarket strap. Always measure the distance between the two attachment points on the case using a digital calliper before purchasing a replacement strap.

For a yellow gold Day-Date 40, alligator leather is the most elegant choice: its natural texture amplifies the nobility of the gold and ages beautifully. Vegetable-tanned calf offers contemporary restraint for those preferring subtlety. Shell cordovan provides unparalleled brilliance and exceptional durability. Technical rubber remains ideal for everyday versatility without aesthetic compromise.

Remove the deployante (folding clasp system) and slide the strap from the lugs using a wooden tool or purpose-designed implement. No case disassembly is necessary. If uncertain, consult a certified watchmaker or Rolex directly, which provides the service at no additional cost. Casati Milano performs strap changes in their Milan workshop by appointment.

Yes, provided the strap strictly respects the 20.00 millimetre lug width and the strap ends are dimensioned for Rolex attachments. Quality artisanal straps employ superior leather and impeccable finishing, often exceeding commercial standards. Trust laboratories with certified quality control, such as Casati Milano.

A quality leather strap (alligator, calf, cordovan) with proper tanning lasts between four and six years of daily wear, provided regular maintenance is observed. Periodic cleaning with a damp cloth and annual application of specific conditioner significantly extend its lifespan. Casati Milano provides an 18-month guarantee against manufacturing defects; thereafter, the strap can be regenerated in the same workshops.
