This was from the last few batches of Cosmo King that used the acrylic crystal. This was produced during the early 1990's. Unlike conventional vintage Cosmo King, this watch has a slight different casing, case back design and bracelet.
The dial is pretty standard Cosmo King's design. The bezel is engine turned design and the case is curved in such a way that it formed protective lugs for the crown.
The bracelet has the typical jubilee look but the links are somewhat flattened. The clasp is still the traditional vintage Titoni signed type.
The case back has evolved into more contemporary design and look quite similar to the latest Cosmo King case back. The movement in this watch is the Titoni assembled ETA-2834-2.
