NO. 25’690, CIRCA: 1890
CASE MATERIAL: 18K gold
CASE SIZE: 55 mm. diam.
DIAL: White enamel
MOVEMENT: Manual, wound by opening and closing the front cover
FUNCTIONS: Quarter repeating, two time zones. The cover winding mechanism was patented by Benjamin Haas in 1873 (English patent No. 3945 of 2 December 1873). The initial concept was progressively improved, as shown in this watch which features a system with a 36-hour power reserve achieved by twelve closings. This new design proved successful and was used in some of Haas’ best watches, mainly in combination with other complications.
The present example, featuring an additional time zone mechanism and a highly finished movement stamped twice with the Geneva seal, was obviously deemed worthy of the further addition of his patented winding system.
It successfully combines both watchmaking prowess and aesthetics and is a worthy addition to a collection of fine watches.
Haas & Cie. was founded by Leopold and Benjamin Haas in 1848 and manufactured from the beginning small series of gold or platinum watches featuring the classical complications such as perpetual calendars, quarter repeaters, chronographs and split-second chronographs. Over the years, new family members joined the company and consequently it was renamed to Haas Neveux & Cie.
In the same year, Haas launched a highly innovative pocket watch with a movement that was wound by opening and closing of the cover. This mechanism was further developed and patented and presented at the 1893 Chicago World Exhibition.
A further asset of this watch is its movement, stamped twice with the Geneva seal. This hallmark certifies that it conforms to the highest official standard of traditional Geneva watch making and consequently stands for workmanship of outstanding quality.
It was introduced by the State of Geneva in 1886 in order to provide a guarantee of the origin and the craftsmanship of clocks and watches made in Geneva. The criteria includes 12 technical absolute requirements related to the manufacturing of the movement. Only manual and self-winding mechanical movements can be awarded the Geneva seal. "
