Omega Speedmaster "Grail" a stylish, practical but rare watch

I've long been an admirer of the Omega Speedmaster, as discussed here. Its robust good looks and history as the only wristwatch worn on the Moon gives it a unique place in wristwatch history.

Various versions of the Omega Speedmaster "Moonwatch"

However, there is a rare Speedmaster which even the most hardened Moonwatch owner would give his (it's usually a man) right arm for. Known as the "Grail" it's superficially similar to the conventional Speedy, but, unlike this watch, which has a manual wind movement, the "Grail" has an automatic Lemania 5100 movement which is renowned for its strength and for the clarity of its dial. As a practical and legible chronograph (a watch which has additional buttons controlling the second hand, giving it a stopwatch function) it has no equal - it has a date, which the Moonwatch doesn't. It's also extremely rare, thus guaranteeing its popularity with obsessive wristwatch collectors, even though the quality if its movement is not as high as that of the Moonwatch.

I am very grateful to "Chinnock" from TZ-UK for allowing me to use copies of the pictures he took of a "Grail" Speedmaster which show the attractive and functional nature of this watch.
