Tudor Chrono question

[chris5150]

just wearing the tudor for a spell....wondering about the chrono counter. Firstly why a 45 min counter?, why not 60 min as per the usual chrono sub dial.
Also why would the area between 50 - 55 mins be highlighted on the dial?...surely it would make more sense to shade the 55 - 60 min area so you can see when its approaching the hour,ie the next 5 min section onwards that would end at 15 mins,cannot for the life of me understand what the purpose of highlighting the 50 -55 min area is at all.
Its a nice watch, really enjoying it currently
knowledgable lot out there so I am sure someone can enlighten me....

interesting...but the orange highlighting is on the 50 - 55 mins , only on that section, it makes no sense why that particular 5 min section has been highlighted. Makes a lot more sense on the one shown above that highlights the three sections
Just seems so odd to make a point of highlighting only that area...when you glance at it you would think that the orange area would be indicating either that last 5 mins of the counter or the starting first 5 mins of it...puzzling, I understand what you are saying, but surely the 45 - 5 mins should be highlighted
