Found this "Barn find" 2998-5 on Ebay

There’s absolutely nothing original about that watch. Well maybe the crud and beat up case.

I strongly suggest that before you bid on any watch that you do a bit of basic research.

For Speedmasters check out the excellent Speedmaster101 articles. For all watches go to something like Chrono24 website to get a good idea of what a watch should look like and what it may be may be worth.

Your watch has a 2998-5 back, case and 321 movement. Wrong dial and hands. No crown or bezel. The case has had a hard time.
Proper alpha hands will cost circa 3,000-5000, dial 3,000 to 5,000, crown 400, DON bezel 800 to 1,500, servicing (without parts needed) 500 to 800. Parts ? All figures in GBP ..... not $! You would be hard pressed to find the proper parts and it would take years.

However, the scrap value of the parts may be worth the current bid if a buyer can be found..
