BIGJIM67 Posted March 23, 2007 Report Posted March 23, 2007 I have my eye on a 16700 case, and already have all of the other parts needed for a 1675 Franken (dial, bezel, movement, hands, datewheel and "TW Best" GMT case). Will I be able to put the 1675 stuff in the 16700 case? Thanks!
eunomians Posted March 24, 2007 Report Posted March 24, 2007 I am not sure if the ETA movement will fit. But your biggest problem is the grossly incorrect 28000bph of the ETA. It is very different than the 1575 movment, and, it it is very noticeable.
FlipLockBuckle Posted March 24, 2007 Report Posted March 24, 2007 ...exactly. The 1575 (Rolex GMT 1675) has only 18000 beats per hour, while an eta has 28800 beats per hour. Maybe you would want to use a usual asian 4 ticks per second movement, to make your frankenwatch look more authentic.
eunomians Posted March 24, 2007 Report Posted March 24, 2007 (edited) The other problem is that there are no correct BPH movements with a GMT function. This is the reason why nobody has been able to replicate a 1675 correctly. This, of course, is good for OEM vintage collectors like me but no fun for those in the rep game. I love my 1675!

What if youd just take the movement out and use that for your frankenwatch project? Edited March 24, 2007 by FlipLockBuckle

What if youd just take the movement out and use that for your frankenwatch project? This asian GMT movement is still useless. The huge reason is because these type of movements have a jerky seconds hand. OEM Rolex 1520, 1530, 1560 and 1575 movements have a smooth sweeping seconds. The asia Miyota-type movement has irregular jerky sweeping seconds. I can spot a Miyota-type movement from a mile away. So can anybody who has merely glanced at a genuine vintage Rolex watch.
Pugwash Posted March 25, 2007 Report Posted March 25, 2007 o-fakes.com have a gmt with a 4 ticks per second asian movement, and it even has the correct handstack. 4 is too low. You want 5/sec.
