This is a truly rare watch... it's the smaller brother of the Lemania/Omega/Tissot Cal 15TL/33.3... Made from the end 30's to the early 40's these Caliber 28.9's were made in much, much lower numbers and for a shorter period. The cases and dials are the same design and parts like crowns, pushers etc are the same as the 33.3/15TL. The example here has a very rare 14K pink gold unpolished case measuring 33mm excl. crown (triple signed). The original dial is also super rare! Pink salmon with red and back printing, various scales and the hour markers are gold mirror. Very nice combo together with the blued hands. The 28.9 movement is very clean, was serviced and is working nicely. Attached is a period style pigskin strap. Very hard to find so get it while you can...
