Up for sale is a rare vintage Waltham Marca Blanco men’s manual wind dress watch featuring a beautiful Art Deco design, gold-filled case, and an exceptionally unique original enamel dial. Unlike standard Waltham examples, this watch is signed “Marca Blanco” and features the Spanish inscription “PAT. 4779. MEX. 10 ENERO 922” beneath the center of the dial. Combined with the Spanish branding, these markings strongly suggest the watch was originally produced for, or retailed in, the Mexican market, making it a scarce and highly collectible export-market variant. The distinctive 24-hour outer track, recessed subsidiary seconds register, and unique dial layout give this watch outstanding vintage character and collector appeal.

The watch is in full working condition and is running and holding accurate time over a 24-hour period. It was professionally serviced in January 2026 and is fitted with an aftermarket burgundy leather strap.

The watch is in fantastic physical condition for its age with signs of normal use and age. The original enamel dial is exceptionally well preserved and remains one of the standout features of this piece. The photos best describe its overall appearance and physical condition.
