Thanks again to all who responded. Very grateful for your advice and thoughtfulness. All points are very well-considered and taken to heart. With respect to accuracy with regards to Marlin's work (I was in a hurry to ask the question), I am including the mods done on this watch although it's outside of the scope of the question. If you site an artists work, it's important to be accurate, especially if he catches you (and the watch is delivered completely regulated):
List of Mods:
1. ETA 6497-1 movement with ETA stamped and with damascening pattern (pearlage or engine turn) on baseplate front and back(this has to be engine turned and nickel plated then rhodium plated as they do not come with the baseplate decorated from ETA) Modded from low beat 18,000 to high beat 21,600 w/ Asian train.
2. Brushed and plated center, 3rd and 4th wheels
3. Changed ETA balance wheel for rep. for more gen. look
4. Brushed setting lever jumper like gen.
5. ETA polished ratchet and crown wheels
6. Replaced upper incabloc shock system with Y incabloc
7. Modded lower shock system
8. Replaced the old inaccurate hands with Gen. like superlumed hands
9. Flattened and polished cannon pin.
10. Replaced thin dagger regulator with thicker on e like gen.
11. Gold leaf text on movement, no more yellow paint
12. Flattened and polished cannon pin.
13. Cleaned, oiled, time regulated, and all seals are silicon greased
