This is a Mido "Multifort" Powerwind Cal. 917P full-rotor automatic waterproof model, featuring a rare black gloss dial, manufactured in the 1950s.
Produced from the 1930s to the 1970s, the Multifort was one of Mido’s most iconic models, available in various configurations, including manual-wind and automatic movements, as well as round and rectangular cases.
This particular piece is equipped with the Cal. 917P full-rotor automatic movement with shock protection. The robust screw-back waterproof case is engraved with "POWERWIND," "ANTIMAGNETIC," "STAINLESS STEEL," "SHOCKRESISTANT," and "WATERPROOF," highlighting its practical functionality. Additionally, the caseback and mid-case share a unique serial number, reflecting meticulous craftsmanship reminiscent of FB cases.
The black gilt dial, featuring applied wedge indices paired with dauphine hands, showcases the high quality and refined design characteristic of this era, making it a truly remarkable timepiece.
