The Seamaster Chronostop is much larger than the Geneve model with the same movement, hence Jumbo. Model reference 145.007

HOW DO WE DATE THIS WATCH?

From the serial number on the movement we can accurately date this watch to being made in 1968.

CONDITION

This Chronostop has the 17 jewel calibre 865 chronograph movement fitted, which is all working well. It is unusual in having a 60 second chronograph and no constant running seconds, and many owners will leave the chronograph hand ticking away until they need to use the stopwatch function. The design does leave the dial unclutters, but there is still quite a lot of detail on the dial. The inner section is dished, with applied hour markers (with slight corrosion) and the gaps between slightly discoloured, something we have seen regularly with this model. On the outside of the dial is a tachymetre scale. The hands, including the distinctive orange chrono hand, are all original. The crown is signed, as is the crystal with Ω logo. The case is unpolished, with the original graining clearly visible, but that also means there are a few marks that haven’t been polished out. The leather strap is new, and could be swapped for a different colour if preferred. The Chronostop Jumbo is an ideal watch for those who are used to the larger modern watches but want to try something vintage. The box has no inner cushion and is in quite poor cosmetic condition, but still better to have than not.

This watch will be supplied with the original presentation box and our Certificate of Authenticity.
