Need some advice,

[offshore 0]

I have had available a set of dies to open the case backs on Brietling models.

The dies available are noted as 36, 38 and 40.

Now one would logically expect they fitted 36mm, 38mm, and 40mm across case backs.

This however doesn't appear to be the case!

So my question is this.

What measurement across the flats do you have for a specific model...and what size do you understand that model to be?

I am already told that a 36 is 37 across the flats, but am now also told that a die marked 36 which was shipped to a client last week, is measuring 40mm across.

So I am a little bewildered.

 

However I am sure there is enough expertise around this place to get some real answers!

If the die says 36, it is likely going to open a 40-42mm watch, as the caseback is smaller than the actuall "watch" measurement.
