Rare Longines 30CH ref 6075 with special dial. These early 30CH's with high pressure waterproof snap-back cases, also called 'Doppio Linguetta' are still very much undervalued. They share the same beautiful 37,5mm case as the 13ZN's. This example was delivered new to Switzerland in 1954 (Longines Extract) and is a rare Non-Flyback version (special order). The beautiful original dial with applied gold numerals and radium dots has matching gold hands. It's a special dial which I've not seen before... Movement is the super high quality 30CH which is in perfect working condition. Attached is period style high quality strap with original Longines buckle. These are great quality stylish watches!!!
