Not going to discuss pricing specifically
But 5270 is part of the high end range whilst the 5960 is part of the generic range of PP.
As far as I know, the level of finishing is different and the complexity of the perpetual calendar mechanism is also higher than 5960.
In a nutshell, to explain the value/market price difference, the 5270 is probably seen as a more collectible piece compared to the 5960.
