Can I destroy a myth? I flew Vulcans from 1975-84. The yellow-faced Seikos were apparently purchased by the MOD in 1983. I read that some 700 were bought. By 1983, there was only 1 Vulcan squadron left (No 50, based at RAF Waddington) with just 50 aircrew officers.
Unfounded rumour has it that the yellow-faced Seikos were purchased because they were easier to see in the dim Vulcan cockpit. The Vulcan cockpit was jam-packed with black instrument dials of various shapes and sizes. There was always more than enough light to see them, AND our black-faced aircrew watches.
The Vulcan came into service in 1958 and the last squadron was disbanded in April 1984. It is illogical to think that the MOD would make a special purchase for watches in the last year of the aircraft`s military life.
The explaination that there are no military markings on the watch "because they were the subject of a "local purchase order" does not ring true. Supply Officers` cash limits for local purchases were highly-regulated and very limited. The cost of 700 Seikos would undoubtedly be well-beyond any "local purchase" limits.
As to the photographs in Charlie`s message. This is a modern-day watch and, unfortunately, I do not think that it has anything to do with the military, despite the stamped numbers on the back. I see no reason why the MOD would purchase an attractive coloured faced watch such as this one. An RAF Supply Officer I know has checked for me and, apparently, there are no such watches anywhere on the MOD inventory.
