*CAL.25-21 is a square movement newly developed around 2007 to reprint and release the Chrono Metro Gondolo REF.5098. It seems to have inherited the characteristics of the movement mounted on the original chrono metro gondolos from the 1920s. Since the famous movement developed in the 1930s and 1940s as a non-round Patek movement, it was the first time in about 70 years that it was developed without complications. Other than REF.5098, CAL.25-21 is mounted on REF.7099 and this model REF.5124. Note that although REF.5098 and REF.5124 are both reverse cases, the shape of the movement appears to be slightly different. This is because in REF.5098, the shape of the reverse window slightly hides the movement, while in REF.5124, the shape of the reverse side window allows all movements to be seen.
*Gondolos are collections of rectangler, tonneau, cushion, etc., and there are no round ones.
* The model name “Gondolo” sounds slightly different, but it seems that this comes from the early 1900s when Patek produced and delivered special models for the Brazilian luxury watch and jewelry store “Gondolo & Lavrio.”
*Most Patek Philippe movements older than around 2009 are engraved with the Geneva Seal. The Geneva Seal is a title given to watches that have strict standards for accuracy, manufacturing methods, and finishes for mechanical watch movements and have cleared them. It is a historic system that actually started in 1886 in response to the passage of a law relating to clock operation tests at the Geneva Observatory. Since it is not easy to obtain a Geneva seal, it can be said that it is proof of high quality watches, but since manufacturing in the province of Geneva is a requirement, it seems that there is also an aspect of protecting the watch industry in the province of Geneva. The accuracy at the time of shipment seems to be about the same standard as a chronometer. Furthermore, since around 2009, Patek Philippe has moved to a unique standard called the Patek Philippe seal.
