16750 and 16550 seconds hands

[Gmt21]

Are these the same/compatible?

Specifically I’m wondering if a NOS 16750 seconds hand that I own is compatible with a 16550 that may need a new hand.

Yes. Fits cal 3075 and 3085 the same. Any 30xx and 31xx calibers movements.


All work done in the good ol’ U.S. of A.

The 3085 movement is found in the GMT II 16760 which has a short tube on the seconds hand.

The 3075 movement is found in the GMT 16750 which has a seconds hand without the short tube.

The 3185 movement is found in the GMT II 16710 which has a seconds hand without the short tube.

The 3175 movement is found in the GMT 16700 which has the seconds hand without the short tube.

The models 16750, 16700 and 16710 all use the same seconds hand.

Thanks for the info Springer, so based on your matrix above, as the 16550 utilizes the same 3085 movement as the 16760 their seconds hands are interchangeable with short tubes, but they are not interchangeable with the 16750, 16700, and 16710 which have long second hand tubes. I think I got it straight now.........
