Thought I might share this rare Lecoultre 8 day pocket watch. It's equipped with a reserve indicator. Unfortunately, the hairspring's damaged.
I'm sure the power reserve works on the same principle as this version of the Futurematic: What is the vintage of that pocketwatch? gatorcpa
9/10 times someone posts a pocket watch its a pretty boring thread but an 8 days power reserve LeCoultre is the 1/10 exception, nice find!
Here's one purported to be from around 1937. http://www.antiquorum.com/catalog/l...ger-LeCoultre&estimate_facet=1000-2000&page=1
