Hi all, My first post here having stumbled across you guys whilst doing research into a Speedmaster I've recently (in the last 18 months) inherited from my father. Having already done some research into the watch I'm trying to get my head round all the various versions of the speedmaster and how these things affect rarity and value. I've read some of the sticky threads, some of the clearly very informed people on here have posted up, but am still struggling to understand various aspects. What I know about the watch is as follows. 1.) It was bought new in Aden in the early 60's by my uncle when he was stationed there with the RAF. He then wore it as a daily watch for approximately 40yrs till he died in the early 2000's. 2.) My father was given the watch by my uncles daughters as a thank you for dealing with their fathers estate and sorting everything out for them. He then somehow realised that maybe this watch was quite rare/valuable and being the man he was, wanted to find out more about it. As part of that research, he sent the watch off to Omega themselves (which I now know was maybe not the best thing to do), to try and find out more about it and also potentially have it serviced. Fortunately (I gather) he chose not to have them do anything to it, but they did check the watch over and supplied him with information (which I cannot currently find) stating that the watch was totally original and nothing on it had ever been replaced. 3.) I believe the watch is a 105.002 model and a friendly omega enthusiast, has told me and my mother that what Omega said seems to be true. 4.) The friendly enthusiast, also said that the watch itself is a relatively rare speedmaster model (which my research seems to confirm), but that it being totally original makes it much rarer and the fact that's it's entire history is known also makes this rarer. This leaves me trying to work out some kind of ballpark idea of how rare this actually is and what the value of the watch is. I need to understand this so I can work out whether I can afford to insure it and keep it (so what value I would need to tell the insurance company), or whether I really cannot afford to and therefore need to sell it, but where I come utterly unstuck is in having a clue what "value" it reasonably has, for the following reasons. 1.) How rare is it for a watch to be totally original, including the bracelet. 2.) How do I appraise the condition, to my eyes, it looks good, but I'm no expert on watches or what collectors look for (although some of the sticky posts have helped on this front). 3.) how realistic are the prices being asked for these types of watches, given the apparently wild variations I've seen and been told (everything from £3-5k) to "probably £15k+ but if you get two collectors in a bidding war who knows. As such what I trying to understand is. 1.) How rare is it? (assuming clearly that it is actually completely original) 2.) Does it look in genuinely good condition? 3.) How do things like rarity, originality and condition affect values and desirability? Does me knowing it's entire history affect this rarity/value? 4.) If I do end up wanting to sell it, how do I ensure that I'm both not undervaluing it, neither am I flying a kite way beyond it's value. 5.) When insuring it, do I just take the value that I think and add 20% or do something else? 6.) How critical is finding the info Omega supplied to my father? I've added some pics below. I don't have the tools needed to remove the back and would be loathe to do so anyway for fear of damaging it Any guidance people can offer would be much appreciated, fundamentally I'm trying to understand what I have..
