I'm NOT certain in the case of Hamilton, but I know this is true of Benrus and some of the others so I just pass this along. Some of the great old names in watchmaking actually left the business for whatever reason. Then years later (now) companies with less stellar credentials have bought the company names and are producing watches using the previously respected name. That doesn't necessarily mean the product won't be good, but it does mean it might not be what you think it is. I bought a couple Benrus watches of this sort. They have been OK. I discovered what I have just recounted through what someone told me and then researching Benrus on the web. I have been told other company names have suffered similar fates.
