how often you hear
using the
same eta 6497.... but they charge you rm 10k more....

this is the swiss made eta 6497-1 base movement -
an ugly non finish movement.
how about this, the so called finish movement u often seen in the RM few k watches.
nickel plated, blued screw, cotes de geneva
and compare to this

are they the same eta 6497?
comparing the movement 2 & 3 (Pam) i can simply point out the obvious differences (not the detail level/degree of finishing), worth the rm10k different.... u judge
1. most vious different - the ugly 6497 bridges has been thrown and replaced with the new bridges
2. plating - nickel vs pam rhodium - rhodium is the ultimate plating for watch movement. the price is also most expensive!
3. base plate finishing - none vs perlage
4. balance regulating - std vs polished swan neck - swan neck not just aesthetic, its easier to to do micro adjustment
5. bridges beveling - none vs yes
6. beat per hour - 18,000 vs 21,600 - arguably the faster the better accuracy
7. power reserve - 40 vs 56 hours
8. accuracy - non chronometer vs COSC
above are the obvious differences... the non obvious could be material of hair spring, balance wheel, polishing on each wheel, blue screw method, fine level of cotes de geneve, how many position is was regulated, etc
with many watch putting the so call swiss eta 6497 into their watches, they may claim the same... most likely they are not!
rm10k++ different justifiable

no? u can go on to compare the other component of a watch...
