Patek Philippe open-face pocket watch, yellow gold chronograph, two-tone sector dial, pulsations scale, presentation inscription to Benito E. Martinez and box, retailed by Walser Wald, made in 1910. 50mm Diameter. Case, dial and movement signed, dial further signed by retailer Walser Wald.

This is the only pulsations openface watch retailed by Walser Wald that has ever appeared on the market. Walser, Wald Y Cia was a retailer in Buenos Aires, Argentina. At the time, it was one of Patek Philippe's most prominent retailers in South America.

The inside of the case back reveals an even more compelling story. It is inscribed "Al Diputado Nacional Benito E. Martinez SUS Amigos Politicos de la VIth Seccion Electoral Pcia Bs As 31-5-1938". It seems that this watch was a gift from the National Deputy's friends, celebrating a moment in Argentinian politics. Research shows that Benito E Martinez was very active in Argentinian politics in the early 20th century, eventually holding a Deputy position in the 6th Section of the Province of Buenos Aires, representing the Conservative party.

As an even nicer touch, the original presentation box not only bears the Patek Philippe name, but also Walser Wald y Cia.
