What size is the crown on a 2594.50? The reason I ask is so I can get the correct size crown winder. Thanks for all the help in advance!
I don't understand why you need a crown winder. The 2594.50 is an automatic watch and any of several watch winders will work for you. My favorite is made by Orbita, but there are other good winders on the market. Here's a picture of the ones I use. They run on battery so they don't need an electric outlet. This setup works well since I store my watches in a safe.
I don't understand why he doesn't just measure the crown since it appears he already has the watch...
