the 292 has been a great success for Panerai, culminating with the 292J "pig" that went out of the doors in...nano seconds. I'm not sure a 47mm model, would have been that successful. 2mm, in normal life seem a pretty small difference but, on a wrist makes all the difference in the world. People, at the time, were still trying to reconcile themselves with 44-45mm, when everything around was in the 36-38mm range. IMO of course
