hi,
i would like to ask a question
anyone is able to tell if the back case of the 910 and 911 are interchangeables ?
thank you
They are interchangeable as far as fit goes, and there is no outside visible difference. However the reference # for the appropriate watch is marked on the inside, so anyone opening it would know if a .013 (910) had been put on a .026 or.036 (911) or vice versa.
From the "flightmaster only" book
Length lug to lug .013 (52.34mm); .026 (52.55)
Width same at 43.10
Thickness excluding glass and caseback .013 (11.10) .026 (11.70)
The other major difference is in the flat vs. curved crystal. Attachment to case is the same, very different in .036
The book is really ESSENTIAL if you want to know all the gritty details about flightmasters. It's the best investment I've made.
+have made some checks
comparing 910 a 415.013
with 911 a 415.026
aesthetically they differ a lot, but dimensions are not so different
case back diameter 910 (35mm) 911 (35mm)
glass diameter 910 (37mm) 911 (36,6mm)
case length 910 (52,5mm) 911(52,8mm)
total thickness from case back to top glass 910 (16mm) 911 (15,7mm)
case width 910 (43,5mm) 911 (43mm)
Your 145.026 carries service bezel and hands. 145.013 with service bezel too.
thank you for your observation
could you please educate me in the significance of this ?
is the service bezel and or hands wrong, incorrect, less valuable, better, a positive thing ?
thank you
They are great looking watches, especially the tropical one, congratulations.
Re the service parts...it’s no big deal, they are genuine replacement parts and should not impact your enjoyment from wearing them. Also I don’t believe it will have a material impact on the price if you needed to sell the watches.

oh, thank you very much for your kind words and detailed explanation,
i had no idea of what “service parts” meant, else than replacements, and more important i am unable to tell that they are in fact service parts, so i was a bit surprised and thankful that someone could notice it from a photo
