The Tissot PRC 100 Solar features a 39mm 316L stainless steel case with a bold dodecagonal bezel and is powered by a Lightmaster solar quartz movement, designed to recharge from both natural and artificial light. A black dial sits beneath scratch‑resistant sapphire crystal and includes an end‑of‑energy indicator for optimal performance. First introduced in the mid‑2000s, this updated PRC 100 retains its distinctive design while offering modern solar technology and compatibility with 20mm interchangeable straps. The watch is finished with a quick‑release system and is presented on a matching leather strap, combining everyday practicality with confident, contemporary style.
