For sale we have a circa 1932 Art Deco 9ct gold ‘digital’ jump-hour dress watch. It has a neatly proportioned case, measuring 22mm x 30mm. The case has a polished finish to the front and rear, with three apertures on the front which display the hour, minutes and seconds discs. To the sides is a diamond pattern engraved boarder, which adds a neat design touch. The lugs are slim and short, allowing for a smooth, square case design, resembling a gold ingot. The hinged case back has British hallmarking for 9ct gold on the inside. It is from London assay office, with the date letter ‘r’ putting it as being manufactured in 1932/3.

The movement is an FHF calibre, with a digital module to the top side for disc modification to display the time. It is manual wind and displays the jumping hour, wandering minutes and wandering seconds. It has been recently serviced and is keeping time to within +/- 10 seconds a day.


The watch has the makers mark of Eyna Holko Podolsky. He was a Ukranian immigrant and the son of metalworkers, being an apprentice jeweller at aged 12, before becoming a skilled diamond mounter, setter and engraver.

He started his own business in 1920 as diamond mounters and watchcase makers, which was known as The British National Watch Case Co. He was subsequently the first man in Britain to go into mass production of platinum and diamond-set wrist watches.

He also undertook orders for other jewellery and commissions from private clients, with over 130 design drawings in his collection, many of which are excellent examples of Art Deco design. 


Originally patented by Pesuex in 1924, this style of jump hour movement is known as “Heures Sautantes”. Time is displayed through small windows in the case, with a combination of “jumping” hours and so-called “wandering” minutes. This evocative design has been made in every decade since the invention in 1924 and continues to be one of the most sought-after styles.


We personally love these early jump hour watches from the 1930s. These perfectly encapsulate the elegance and innovation of the art deco period, whilst maintaining an element of subtlety with the clean and integrated design. The design makes time telling a very personal and hidden experience, with the traditionally large watch face being traded for small windows.
