Strap for Tangaroa Three-Hands Lady Diamond / White Strap

The lug width of the 2947.50.61.1293 is 20mm. This specification is exclusive to the model and ensures optical proportion with the 32mm case diameter. To verify your measurement, position a digital calliper perpendicularly to the case lugs and measure the internal space between both attachments: the reading must correspond to 20mm for compatibility and secure wear.

The choice depends on your lifestyle and desired proportions. For formal elegance, we recommend natural alligator with developing patina or vegetable-tanned calf leather. If you seek functional versatility, a heavy canvas NATO or FKM rubber strap preserves the original tool-watch identity. For extraordinary longevity and ageing character, shell cordovan represents the lasting investment. All these materials are available in 20mm lug width at Milano Straps.

The 2947.50.61.1293 features an integrated bracelet: the case, by constructive design, does not permit standard removable lug bars. To wear an alternative strap, you must consult a specialised horological artisan for dedicated lug bar installation, or contact Casati Milano atelier, which offers bespoke solutions tailored for this specific model. Milano Straps provides straps ready for professional installation.

Yes, an aftermarket strap with 20mm lug width is formally compatible with the 2947.50.61.1293's nominal dimensions. However, given the case's integrated bracelet, installation requires specialised technical expertise for lug bar adaptation or minor structural interventions. Milano Straps supplies certified 20mm straps; we recommend assistance from an authorised Eterna service centre or specialised craftsman to ensure safety and attachment longevity.

Durability depends on material and daily use. A vegetable-tanned calf strap typically resists 3–5 years with moderate wear; natural alligator maintains structural integrity for 5–7 years; shell cordovan, with proper care, exceeds 15–20 years whilst developing noble patina. Excessive exposure to humidity, direct sunlight and perspiration accelerates ageing. Milano Straps recommends periodic rotation between straps and dry storage to maximise longevity. Worn straps can be restored by specialised craftsmen.
