In general, the Atmos II, 519, 529 take unique parts. The 522, & 532 take all 526/528
parts accept the escape wheel, which is a 519 part. The 540 and higher all take 540 parts.
The movement caliber number is usually stamped on the front plate
of movement (see repair guide for location). Another location is
found on the bottom of the case, please be sure to lock the
pendulum before you look for the caliber number located on
the bottom of the case. The following are the most popular
caliber numbers:
Movement Caliber:
Cal. 540
Cal. 532
Cal. 529
Cal. 528
Cal. 526
Cal. 522
Cal. 519
Cal. Atmos II
The Atmos II and the 519 are not marked for their caliber, the distinct
difference is that the Atmos II as a "knob" for adjusting the fast and slow.
Atmos II's and caliber 519's can be identified by the fact that their fork has
a large rounded "apple" end.
The Atmos II and caliber 519's can use most of the parts and
their number listed here. Please see 519 parts list for a
complete listing for those parts and part numbers. Specifically, the
Atmos II and caliber 519 MUST take unique parts for each of the following:
Barrel # 3820
Barrel arbor # 3821
Movement plate # 3824
3/4 plate # 3825
Fork # 3826 & # 3827
Third Wheel # 3832
Center wheel # 3833
Escape wheel # 3835
Clicks and pulley assembled # 3875
Arbor and ratchet assembled # 3877
Roller # 3879
Intermediate wheel # 3886
So, generally speaking all movement wheel and plates are
different with the one exception of the fourth wheel, which is the wheel
that carries the minute hand. Virtually all other parts are interchangeable.
The two below are in the frame and not in the actual movement.
The gears are arranged as follows:
# 3481 the mainspring barrel
# 3497 the intermediate wheel
The movements gear follow:
# 3400 Center wheel (The intermediate wheel drive this movement gear.)
# 3401 Third wheel
# 3402 Fourth wheel (The minute hand attaches to this gear.)
# 3409 Escape wheel
# 3410 Pallet fork and staff
The following is all the information I have on obtaining Atmos parts.

The following is a complete list of the Atmos parts for the calibers 522 through 532.
The caliber 540 was a complete "overhaul" from the previous design and their part
numbers are totally different. I have a separate listing for 540 parts .
