Minty black dial Lemania Chrono... 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 super sharp step case measuring 33mm excl. crown. The original black dial is in very nice condition with radium numerals and hands and multicolor print. The 28.9 movement is very clean, was serviced and is working nicely. Attached is a period style strap in brown/green matching the radium. Very hard to find so get it while you can...
