Omega Speedmaster or Speedmaster Alaska: Spring Bar to Spring Bar Distance?

[Dualmonitors]

Dear All:

I'm trying to order a custom strap for my Omega Speedmaster Alaska Project, which will soon arrive. In the meantime, the custom strap maker needs measurements and one measurement that would help in this process is the spring bar to spring bar distance, i.e. from the middle of the 12 o'clock spring bar to the 6 o'clock spring bar.

As I do not yet have the watch (in shipment), may I please ask the knowledgeable folks here to see if anyone might be so kind as to measure their Omega Speedmaster for me please? Ideally, if it were an Alaska Project, it would be a sure thing, but I believe that all these modern Speedmasters have similarly sized cases (yes/no?) as the Alaska Project, right?

Thank you very much in advance.

I thought the Alaska project is the same case as the Professional. Spring bar to spring bar on my Professional is 43mm +- 0.5mm (I'm using a ruler not calipers).
