Finally, after nearly six years together, I let my honey out of my sight for a long overdue movement service... now she's back... her ticking heart within COSC standards! Two weeks apart felt like two years!!
At least I wasn't left quite on my own, I had her sister to keep me company!!
Mk II "Patent Pending" DRSD (1665/2.24m) and Mk II DRSD (1665/1.76m).
As an interesting anomaly, I have noted that many Mk II DRSDs with 1.76m case numbers appear to have been released in the early 1970's and have hacking movements... the later case numbered Mk II PP DRSDs were released earlier, and have non-hacking movements...
