Technically ALL Speedmasters are ‘racing’ as there is where the Speedmaster originally got it’s roots before it became the Moonwatch. But once it became the Moonwatch, that is what it was to be know as, forever.
Now the racing versions are just stripped down Speedmasters with flashier dials. They remove everything that makes them a Moonwatch (the 1861 manual movement and hesalite) and throw in a cheap modified ETA movement and sapphire. They are very similar to the Speedy Reduced.
The the history, the icon, the prestige, etc… that make people desire a Speedy Pro and keep the value constant are all missing. Since ’67 until today, the Moonwatch is nearly unchanged. The Racing versions change all the time and have no real history to speak of.
The new racing with 3300 movement is a good value for the money. It comes with the new bracelet design, sapphire, co-axial escapement and COSC certification. I just do not see $2600 as a good price. Look for a LNIB used version for much less.
