This page is really for other models which I don't have a full set of photos of and Doxa items which don't fit anywhere else. I'm grateful to Thomas Pedersen for 4 of the images below and Fredrik Karlsson for the others. I didn't know that Doxa produced a SUB 200 (note no T), which looks exactly like it's big brother 300 and 300T. The Quartz 250T Sharkhunter is also an interesting piece that you hear very little about. I have also included a photo which shows the relative case thickness of the various models. The top one is the original Synchron SUB 300. In the middle is the Doxa named SUB 300T, and on the bottom is the SUB 300. There was a considerable design change to the case over the model history.
The purple box was obviously for a Synchron issued watch. It is not known if it was for a SUB or one of the other watches produced at the time. The blue watch box was for the original Synchron Doxa SUB 300T and the wood grain effect box was for the original Doxa SUB 300 model.
Lee Ward, sent me the photo of the black faced Princeton Tectonics TEC 1800. It is a 600m quartz watch. Look familiar? Take a look at the Quartz SUB 600T Professional on the other models page. It seems that Doxa either produced the Princeton watch for another company or Princeton "badge engineered" the watch supplied by Doxa. The watch was produced in the 1980s and originally came on the standard SUB link bracelet. The bracelet has long since fallen apart. The original bracelet supplied with the SUB models was certainly eye catching but was rather weak and prone to breaking. This is one of the reasons Doxa went for a different design on the re-issue models.
