Strap for Polo 40 White Gold Full Diamond

The lug width of the Piaget Polo G0A36226 is exactly 20 millimetres. This dimension is specific to this model and is not interchangeable with 18mm or 22mm straps. Measurement must be taken with a digital calliper on the internal width of the spring bar sleeve that passes through the lug hole. A precision of ±0.2mm is acceptable, but larger deviations will result in unstable wear and risk of case damage.

The ideal strap depends on intended use: for maximum elegance, we recommend alligator leather with vegetable tanning in cognac or dark brown tones, which creates harmonious contrast with the white gold case. For formal business contexts, cordovan-grain calf leather in black or burgundy maintains sobriety. For daily functionality and marine environments, a technical NATO or grey-anthracite elastomer offers moisture resistance without aesthetic compromise. Each choice must account for the natural patina of the watch and its intended wearing context.

Strap replacement requires extraction of the spring bars from the case lugs. Use a dedicated tool, such as a stainless steel spring bar remover, to prevent scratching. Position the watch on a soft surface (felt or rubber). Insert the tool into the spring bar hole and push towards the opposite side to release the bar. Once removed, slide out the old strap and insert the new one, verifying that the spring bar clicks into its new seat. This procedure requires precision and, if inexperienced, it is advisable to consult a specialist such as Casati Milano.

Any strap with 20mm lug width is compatible with the G0A36226, provided that build quality aligns with the watch's luxury standard. Milano Straps offers straps in alligator, calf, shell cordovan and NATO, each available in colour variants. Compatibility extends beyond dimension: it is essential that strap thickness (typically 3.5–4.5mm at the lug attachment) does not cause abnormal pressure on the case shoulders, and that the buckle (ardillon or deployante) is proportionate to case dimensions.

A quality leather strap (alligator or calf) typically lasts 5–8 years with regular wear and proper maintenance. Longevity depends on factors such as wearing frequency, sun exposure, contact with water and perspiration, and periodic care routines. Applying conditioning creams every six months, avoiding prolonged soaking and protecting against direct heat sources significantly extend useful life. Vegetable-tanned leather develops a prized patina over time, whilst industrial tanning tends to crack. A rubber or NATO strap maintains superior performance in marine environments and under continuous mechanical stress.
