Hi all, I was looking up watches and noticed the relatively high prices of the 6r series, and the cheapest ones I come across so far fall within the 400++ USD range. It made me wonder about the difference between the 6r movement and the 4r movement. I understand that the 6r movement is largely similar with the 7s movement, except that it has the ability to handwind and hack.
I read on another post that the 4r15 movement does not allow the handwinding or hacking, but my 4r36 on my SRP151J certainly allows me to do both. If my relatively cheap 4r36 movement already allows me to handwind and hack, what would be the incentive for someone to upgrade to the 6r series? If it is the accuracy factor, then I am still not convinced, as my SRP151 already gives me -2 / +5 seconds a day depending on how I rest the watch when not in use.
Can anyone here give a detailed explanation regarding their differences? Thanks!
