For sale we have a beautiful example of a versatile 1940s Rotary tool watch, in excellent condition. The watch has numerous high quality and attractive design cues, which make it a re-assuring and enjoyable presence on the wrist.


It has a well-proportioned 33mm case, with a good lug-to-lug length of 40mm. It is chrome plated with snap on steel back. It has neatly tapered lug design and a neat side profile with the thin central section of the case. It has a mix of brushed and satin finishing to the case which adds to the complexity of the case design.


The Sector dial is well designed with a satin shine to the centre and a matte outer chapter. The dial is surrounded by a beautiful rose gold tone foil boarder which shines in the light. The sub-second dial is inset, with textured concentric circles adding texture. The second graduations are clear, with Arabic 15 second markers and dashes with the railroad track. The Rotary signing is well executed with the underlined R, connecting to the Y. The lumed Arabic numerals are original and have aged to perfection.


It has wonderful thermally blued syringe hands and a stylish and unique dagger sub-second hand design. To the right is the original dimpled crown which rounds off this stylish tool watch. Equally adept as a tool watch or on an evening, this is the mid-century goldilocks watch.


Inside is the recently serviced manually wound Rotary calibre 620 movement, ensuring reliable timekeeping.


Study the images, enjoy them and notice your eye be drawn to all the small design touches, that add up to an impressive little watch.
