This is a beautiful 14k yellow gold octagon design rectangular model with a yellow Breguet dial, manufactured in the mid-1920s by Gubelin. It is a rare rectangular model made by Longines, a company that seldom supplied to other brands. It features the early rectangular movement Cal.9.47, known for its superb finishing and graceful curves. The 14k solid gold octagon design rectangular case shares construction details with contemporary Longines models, such as the unique number engraved on the case back matching the movement.
The dial, also similar to those found in Longines watches of the same era, has a soft yellow color with applied Breguet numerals, exuding a sense of luxury. The yellow dial and yellow gold case, known as the "yellow on yellow" combination, showcase a stunning color harmony and vintage aesthetic. The dial, case, and movement are all signed by Gubelin, without any Longines markings.The mechanism is engraved with the number of jewels and five-position adjustment, which is not found in Longines.
