|DateYourIWC is a utility which let you derive date of origin and some other production information from the movement and/or case number of watches produced by the International Watch Company, Schaffhausen (IWC).
The availability of sources dictates that the application works best with vintage watches produced prior to 1975. The later the period, the scarcer and more circumstantial the evidence becomes. Even at its best, DateYourIWC can only offer you tentative results. If you need a truly reliable dating of your IWC timekeeper, there's no other way than to order an archive extract from IWC.
You can choose between three different formats of DateYourIWC:
Prior to using DateYourIWC I strongly recommend that you read the helpfile that integrated into the Standalone or Online version of the program.
|Standalone is the classic version of DateYourIWC offering all the functionalities of the tool. You have to download the application and install it on your computer.
Pros: well-tried and reliable, once installed it works independently from any internet connection
Cons: Windows or MacOS X needed, data is not automatically updated; resides on you computer, hence may not be available when needed on a shopping tour or trip
To download DYIWC standalone click on one of the below links:
Windows version 2.0
Mac OSX version 2.0 Unicode (larger)
Mac OSX version 2.0 Intel processor (smaller)
Mac OSX version 2.0 PPC processor (smaller)
|The Online edition of DateYourIWC uses the same code as the classic standalone program. In this case however, all the data and most of the logic resides on the web server. You run DateYourIWC Online in a window of your browser using a special web plug-in made by RunRev (similar to a Flash plug-in). While this approach poses some limitations (e.g. you cannot open multiple windows at the same time), all important functionalities are still there.
Note: When first using DateYourIWC online, you will be asked to download and install the Revweb plug-in. Please follow instructions given during the installation.

|The DateYourIWC Applet is a true internet application, i.e. all the code is executed on the web server and only the results are transferred to your browser. This comes however at a price, for just the basic "dating" functionality is available in this version.
Pros: data is always up-to-date, works on all devices which have internet access, i.e. also on most mobiles
Cons: requires active internet connections, limited functionality
