Frequently asked questions
What is the lug width of the Rolex Pearlmaster 81338-0093?
The Rolex Pearlmaster 81338-0093 features a lug width (ansa) of precisely 17 millimetres. This measurement is specific to the Lady Pearlmaster 34mm model and is critical when selecting a replacement strap: it represents the internal distance between the two spring bar attachments positioned on the case lugs. Always verify that your strap is calibrated for 17mm, not 16 or 18mm, to avoid structural tension.
Which strap material is recommended to pair with the Pearlmaster 81338-0093 in yellow gold?
For such a sartorial luxury timepiece, alligator leather (preferably Mississippi or Louisiana) represents the classical pairing: the natural grain dialogues with the mother-of-pearl dial and amplifies the jewellery-like perception. An alternative of great refinement is shell cordovan, equine leather that develops profound patina over time. For formal contexts, high-quality calf with vegetable tanning offers finer grain. Rubber or textile straps are inadvisable: yellow gold demands material nobility.
How do I change the strap on my Rolex Pearlmaster 81338-0093?
The Pearlmaster utilises standard 17mm spring bars. To replace the strap: 1) obtain a spring bar tool (specialised implement with a slot that engages the spring); 2) insert the tip into the lower spring slot; 3) press downward until the attachment disengages; 4) slide the strap toward the opposite lug; 5) repeat for the second spring bar. We recommend performing this operation on a soft surface (watchmaker's mat) to avoid accidental scratches on the yellow gold case. If uncertain, entrust the task to a certified watchmaker or Casati Milano's service.
Is an aftermarket strap compatible with the Rolex Pearlmaster 81338-0093?
Yes, any strap manufactured for a 17mm lug width is compatible with the Pearlmaster 81338-0093, provided the spring bars are of identical cross-sectional thickness (standard 1.8mm). Artisanal straps in alligator, cordovan or calf crafted by ateliers such as Casati Milano guarantee construction quality consistent with your timepiece, without any compromise to legitimacy. Avoid generic low-quality straps: yellow gold merits noble materials.
What is the lifespan of a leather strap on the Pearlmaster 81338-0093?
An artisanal leather strap of quality, with vegetable or ennobled animal tanning (alligator, cordovan), has an average lifespan of 3–5 years if worn daily, or 5–8 years if used occasionally. Determining factors include sun exposure (which desiccates leather), contact with water and perspiration, and finishing quality. Well-maintained shell cordovan ages magnificently and improves over time. Casati Milano offers an 18-month warranty against manufacturing defects, but recommends periodic maintenance: gentle cleaning and conditioning with vegetable oils every six months.
