10BT is not the real movement model,I don't know the movement model becouse I don't have open the case.
Can you see how it has been pushed from the outer case? Well now you can get a narrow blade and get it in at the joint with the case back and wiggle gently till the crystal pops off, then follow "easy two-part stem removal" instructions, found in General Information archives in the Forums database.
I have no problem with this ID in light of the diamond embellishment, which was apparently added to the original dial without otherwise doing a redial. IMO the record needs to list the actual movement model (10BT entered on assumption of owner) and could use a couple more photos and updated root data. I'm waiting to assign ticks to see if mustang can update the record. Mustang, if you can't get the watch open w/o breaking it, don't worry about my requests. I think you could get the back off w/o taking the movement out and maybe confirm type and take a pic or two. I wouldn't actually remove the stem and pop out the crystal yourself, unless you've done these kind of things. We don't need that much info!
yea got it now Bob. I see now. I thought the back may screw off w/o having to remove all the other stuff. I looked at Gerard's picture- all disassembled- and the part of the case back w/ the dimple for the stem wasn't in the field of view, and I thought it may be unscrewed from the back somehow- I've unscrewed case backs w/o "grooves" for the tool to remove the backs by using a square piece of a rubber bicycle tire innertube and some elbow grease- but that won't work w/ that stem assembly/opening.
