I dug out a 2846 to service and install as soon as mine gets here! I have one Yuki tube left so I just need to keep a watch on fleabay for a decent used crown and I'll be all set!
I love it, fantastic looking watch with all the functionality of a Daytona and calendar to boot! Although mine aren't "Big Blocks" they are among my favorite watches.
A couple mildly interesting things I discovered on this yesterday:
1. The band is a bit over 22mm.
2. The case back takes the same wrench/die as the DSSD. The gen case back looks to take a Sub size die...
