Check Chrono24.com. There are a ton of SMPs there for sale, and that should give you an idea of what you can consider asking for yours. (Keep in mind, the prices on Chrono24 are asking prices, not necessarily the price the watch will end up selling for.) Some factors to consider: newer SMPs have a co-axial movement, which yours does not have. Yours does have a bezel style no longer avaialable, which might make it more desirable to some buyers. The overall external condition is fair at best. Also, when was the last time the watch was serviced, if ever?
