Thanks Ethan, that shows the difference of orientation of the sub-dial between the two cases, yours that is 45% off-set from perpendicular works nicely for either open face or hunter configurations with the sub-dial at 6'o'clock & pendant in the correct positions of 12 & 3 o'clock respectively

With Muckle's design, when the watch is altered to the open face position you have the pendant at the 3 o'clock instead of at the 12 o'clock position (sidewinder). One of the problems once they went from key-wind to stem-winding watches

WOW Is this site amazing or what!
