Hamilton - A British Military RAF Issued - 6B-9101000-H 3111M - Mark XI Watch

This item has now sold

Hamilton's British Military RAF Issued Wristwatch  also known as the Hamilton Mark XI or 6B-9101000-H

Enthusiasts refer to it as the “Hamilton Mark 11” because it was manufactured for the British government at the same time as its famous brothers, from IWC & JLC to the same RAF specification, and has the same features, apart from these not having the hacking feature. It is believed that only around 3200 examples of this watch were issued according to discussions on the Military Watch Forum (MWR) which makes them highly desirable compared to the circe 9000 IWC equivalent pieces. Currently owned by the enormous Swatch Group, Hamilton can track their history back to 1892 in Lancaster Pennsylvania and were an American manufacturer until 1969 with headquarters now based in Bienne, Switzerland. 

What’s On Offer

This “Mark 11” benefits from a few classic attributes that you would expect to see on a vintage military watch. These watches utilise Arabic indices, an outer seconds 'railtrack', broad arrow and sword hands. Naturally as you would also expect and signified by the circle and 'T", the dial and hands are lumed with Tritium so they can be clearly visible in blackout situations. The lume markings on this particular dial have turn a stunning vanilla colour, as has the triangle at 12 o'clock!

The stainless steel case still has sharp, crisp edges and shows very few battle scars although it will have seen action on the wrist of a member of the British Royal Air Force. As with the case top the case back is also unscathed and still has all its original and sharp military engravings. This is watch number 3111, which is probably one of the last batch of these issued, possibly explaining its stunning condition!

Inside the case sits the cal. 75 Hamilton movement, which is fresh from its service by the renowned watchmaker John Senior so rest assured this watch will run exceptionally well for years to come as it was only just done in January 2021.
