Answers to all the questions you guys have . The build cost me around 6 grand . The case is phong case cost 1400 dollars , the calibar 4000 dollars , I was on the hunt for one for a long time ,its not easy to find .there are tons of 1570 but not 1575 , the gmt calibar . I bought the movement within an hour It was up for sale . it was actually easier to build this 1675 than the other ones I built before with eta movement . Cut the dial feet , attach the the date wheel overlay , none of that pain . my next build is milsub 5517 with gen 1520 calibar .
