Eterna Skeleton Limited Edition 499 Pieces Ref.6773500.69 Eternamatic Automatic Full Set
This is a Ref. 6773500.69 Eterna-Matic Skeleton, released in 1992 by Eterna, limited to 499 pieces.
This automatic skeleton model is rarely seen on the market and is quite a collector's item.
Furthermore, a complete set including the guarantee card, warranty, and box is also quite rare.
Eterna-Matic is famous for Eterna, and the incorporation of five ball bearings was quite groundbreaking at the time. The five ball bearings are even featured in the logo.
It's also well-known that the famous ETA company was originally Eterna's movement manufacturing division, which shows how much effort they put into movement manufacturing.
This model has a very special specification and is incredibly beautiful to look at.
The thin movement is boldly skeletonized and engraved.
Both the front and back are skeletonized, allowing you to admire the beautiful movement.
The Eterna-Matic on the back and the skeletonized rotor are beautiful, and the calendar on the front also has a very beautiful design.
Overall, the condition is very good.
The case condition is generally free of major dents or scratches, with only minor scuffs, making it in excellent condition.
The glass surface is free of noticeable scratches or chips and is very clean.
The hands and the double-sided skeletonized movement are also free of dirt, and the overall condition is very clean.
The buckle is Eterna genuine GP, and the band is original, though with some signs of use.
