Gen movement for 1655 GMT ...

[Martyd3]

What's the difference? Is it just the addition of the hour wheel for the GMT hand or is it more involved?

Thanks.

I'll let the movement experts chime in but I do know most 1575's are marked 1570. How's that for confusing!

It is 1575. But they all marked 1570 as it is a modified 1570. More than just adding the 24Hr hour wheel, more parts are needs to take care of the date changing mechanism as well.

I like to think of it as:

1570- no date

1575- date

1575GMT- date w/ GMT hand

All are decended from the 1530 which first appeared around 1957- followed by the 1565, 1520, etc.

1570 is a chronomter movt. as is the 1565, others typically aren't, but like the James Bond movie, w/ Rolex, 'Never say never!

Anyone know the parts necessary to convert a 1575 date to a 1575 date GMT?

Based on my experience converting a 1030 to 1036gmt (I have never worked on or converted a 157xGMT), in addition to the expense, you are likely to have trouble locating some of these parts.
