At this point the Speedmaster Reduced has been discontinued for around 7 years, so the answer to the question "does it need servicing" is invariably yes, unless it has a receipt from a qualified watchmaker within the last 5 years.
What happens with these, especially the more basic and common black dial ones is that people wear them for years and years then dump them on eBay or a dealer rather than pay the servicing bill, this is especially true of any from eBay dealers as there is no margin to be had at all in servicing one correctly then trying to sell it at a profit. I've actually seen the same ones get passed around like a hot potato in the low 900-1200 range repeatedly badly in need of a service but never getting one as it makes more financial sense to unload it and buy another watch than pay the cost of an overhaul on the reduced.
And for anyone else finding this thread off a google search, if a seller says one of these is in good running order and keeping perfect time but it has no service receipt, you're in for a bill.
