Strap for Frank Sinatra Lady Date Stainless Steel / Black

The lug width of this model is precisely 14 millimetres. This specification is also encoded in the reference number itself (the "14" preceding "97FC"). When selecting a compatible strap, always verify that it is certified for this exact width, as even 0.5 millimetres of deviation will prevent proper attachment to the case lugs.

For this model, a high-quality alligator strap or vegetable-tanned calfskin represents the most harmonious choice, as their natural grain dialogue elegantly with the balanced proportions of the 29-millimetre case. A cotton NATO strap offers versatility for casual environments, whilst satinised rubber ensures practicality in dynamic contexts. Selection depends on your primary usage and personal aesthetic preference.

Strap replacement requires a specialised tool: a spring bar tool. Position the watch on a stable surface, locate the metal spring bars that support the current strap within the case lugs, and use the tool to gently compress the bar and release the strap. Align the new strap's holes with the spring bars and release the compression mechanism. If unfamiliar with this procedure, the Casati Milano Atelier provides professional assistance by appointment.

The lifespan of an alligator or calfskin strap depends on usage, care, and environmental conditions. With vegetable tanning , a well-maintained strap functions excellently for 3–5 years of regular wear. Prolonged exposure to moisture, perspiration, or direct sunlight accelerates leather deterioration. Periodic cleaning with a damp cloth and application of specialist balms significantly extend longevity. NATO and rubber straps offer superior durability, lasting ten years or longer.
