I still don't really get it today, before I always thought the dial, from Tritium dial to luminova, but someone told me early 3570 has T dial too [is that true?] so I'm too confused about the different of these two models how to separate them without checking the cal. ? thanks in advance, willing to learn more
the only time the 3570 had a tritium dial was during the transition to superluminova around end of 1996/ early 1997 so you might see a tritium dial on a 1861 movement but from my memory the 1861 marked the beginning of the 3570.50.
okay, so there is really a small amount of T dial 1861 3570.50 speedy exist thank you for your reply its really helpful
