Baume et Mercier Watch Riviera Automatic Chronograph M0A10826. The Riviera chronograph 10826, inspired by the 43mm version, joins the collection in a slimmer 41mm format. Its dodecagonal case in polished and satin-finished stainless steel is protected by an anti-reflective sapphire crystal. The blue dial with a wave pattern, featuring snailed counters and snailed minute track, highlights the Roman numerals, indexes, and rhodium-plated hands with white Superluminova. It is equipped with an automatic movement with a 48-hour power reserve and water resistance to 10 ATM. The interchangeable stainless-steel bracelet features a reliable system for tool-free changes.
