Partially verified

This Enicar Ultrasonic is a vintage mechanical alarm wristwatch dating to circa the 1960s. It features a gold-plated case measuring 34 mm in diameter with two crowns positioned at 2:00 and 4:00 to operate the alarm mechanism and timekeeping functions. The cream dial displays applied faceted arrowhead markers, an Arabic numeral at 12 o'clock, dauphine hands, and a central alarm pointer with a blue-accented tip. Fitted with an acrylic plexiglass crystal and a brown leather strap, it is driven by a 17-jewel manual-wind AS 1475 calibre movement with Incabloc shock protection.
