While I hear you, I would say that it's marketing and meant to be taken with a grain of salt. As with everything in life, temper your expectations, don't believe everything you read, and most importantly do your homework. No rep is perfect. We know this. "Ultimate", however, seems reasonable. The UPO, for example, is the ultimate PO rep, right? Would you agree that it's the best available PO rep? So it is the ultimate (but still not perfect). 1:1 is perhaps the most controversial, IMO. 1:1 to me means case and case part dimensions in relation to the gen. It should also refer to hand lengths, dial marker sizes, etc. I don't ever expect perfection in every aspect of a 1:1 rep though, and yet I still think 1:1 is not only a reasonable term if used truthfully to refer to CNC dimensioning, but also a necessary one because I DO want to know when a rep has been designed based on gen dimensions...
