I saw this on ebay cheap and it looked very rough but intriguing. I fully expected it to be a quartz but was pleasantly surprised to see a gorgeous copper 11ANC 17J movement. I was able to save the crystal and had to polish off some type of finish that was peeling off the case. It came out great. A new crown and service and she is looking very attractive. Here are the details.
This is a 1976 Bulova Railroad or 24 Hour style watch. It has a brushed yellow gold plate case the a stainless steel screw down back and inner metal dust cover. The dial is a vertical white linen stripe with yellow gold applied hour markers and printed red 24 hour markers. The movement is an 11ANC 17J movement with an N6 date code. The stainless steel back has no markings on the inside but on the back has a N6 date code along with Bulova Shock Resistant Antimagnetic Stainless Steel Back. This is where it gets interesting. It also has "Waterproof". It was my understanding that "waterproof" was banned in the mid 1960s but this might be a U.S. thing only and this could be a non-U.S. model. The back is clearly correct to 1976 as the N6 date code is on it. I cannot find any ads remotely close. The only dials like this all seem to be Accutrons. I look forward to your thoughts on this one.
