Gruen Precision Autowind

Today's watch is my second by Gruen, but the first mechanical watch I've blogged by them.

This model is an automatic mechanical watch in a rounded rectangular case. Inside is a 25 jewel movement, but there is no model number anywhere on the watch, and it is a reasonably smooth movement with a 14,400 bph frequency.

The watch has a 3 hand dial, with a date window at the 3 o'clock position. The face has hour numbers, but starting at 13 rather than 1.

The Gruen company was founded in 1894, but ceased to be a family business in 1953. After this date, the manufacture was done in Switzerland, with a head office in New York, until it closed down in 1977. The Gruen name was then sold, and watches are still manufactured, but with no link to the original company.

There isn't much more information on the watch except that it is a Gruen Precision model which I guess means it was a high end model. It also states that it was Swiss made which makes it before 1977, and I'd guess this is a 60s or 70s model. The back only states that it is a mixture of stainless steel (back) and base metal (bezel).
