The Tartaruga LWT21001, seen from the bench

The Ligure Tartaruga LWT21001 features a 41 mm stainless steel case combined with ceramic bezel and lugs, powered by a Sellita caliber SW200-1 automatic movement. The watch includes hours, minutes, seconds and date display with 4 Hz frequency and 38-hour power reserve. The lug width is 22 mm, a deliberate choice to enhance strap-to-lug contact stability and accommodate thicker leather options.

Frequently asked questions

What is the exact lug width of the Ligure Tartaruga LWT21001?

The lug width of the Ligure Tartaruga LWT21001 is 22 mm (measured from inner wall to inner wall of the groove). This dimension requires a specifically sized strap, incompatible with standard 20 mm lugs. To measure accurately, use a digital calliper positioned perpendicular to the spring bar.

Which strap is recommended for the Ligure Tartaruga LWT21001?

We recommend Tuscan calf from vegetable tanning in midnight blue, or alligator in medium grain. Both enhance the nautical theme and complement the ceramic bezel. For sports use, a midnight blue NATO is a technical and versatile alternative.

How do I change the strap on my Ligure Tartaruga LWT21001?

Strap replacement involves removing the spring bars from the lugs. Using a dedicated tool or small knife, press the spring peg, extract the bar, then insert the new strap into the groove. For the 22 mm LWT21001, ensure the new strap's width is proportionate and the passants are adequately thick.

Are aftermarket straps compatible with the Ligure Tartaruga LWT21001?

Yes, any artisanal strap with a 22 mm lug width is fully compatible. Verify that the passants are not less than 4 mm thick to avoid lateral movement. Milano Straps crafts straps to specification for this dimension.

How long does a leather strap last on the Ligure Tartaruga LWT21001?

A Tuscan calf strap from vegetable tanning typically lasts 3–5 years with standard care (quarterly cleaning, air drying after moisture exposure). Alligator and crocodile leather lasts 7–10 years. Longevity depends on usage, sun exposure, and humidity; leather naturally ages, developing patina over time.
