Property of the original Spanish Family. Consigned from the original Spanish family, these perpetual calendar pocket watches are extremely rare. In fact, so rare that the watch bearing the movement number 48’800. It is also interesting to note that despite being so close, the sale date is separated by more than 15 years, showing how small the production was. Kept in very good condition, the slim case features a recessed bow to discreetly integrate the correctors and an elegant bezel with enamelled Roman numeral indexes, all still present, a clear indication of its overall superb condition.
