How to Research History

[Deezel00]

I have begun to investigate the history of a Rolex watch that has been passed down to me through my late Grandfather. From what I can tell it is a model 1803 and it was purchased around 1973. Can anyone give me some advice on how to find out more about this watch. This is my first post and an not sure what forum, etc. I should be looking in as there is so much information.

Well the 1803 Daydate started life around 1959 with the Cal 1555 18000BPH movement.Around 1965 the movement in the 1803 was modified into the Cal 1556 now 19800 BHP (beats per hour) this carried on with the 1803 till around 1976/77.When after the model changed into the 18038 with the new 3055 now a modern day 28800 BPH movement.Now IMHO the 15XX series movements are the finest Rolex has made well over engineered, and bullet proof in the running.The serial between the lugs will give a better date whan the case was first stamped.

There is a wealth of information on the watch..

Serial number on one side, and model number on the other.. Inside the case yours may have a stamp for the manufacture date ( such as IV72 for 4th quarter in 1972), etc..

You need these to be able to start your research............
