We are proud to present our fifth collection – the Nº 1940 green automatic aviation watch.

It marks the Battle of Britain, referencing the military campaign of the Second World War. The Royal Air Force defended the Britain against the German Air Force attacks from the end of June 1940. The signature silhouette takes on an aggressive aesthetic by looking to aircraft gauges of the era.

The Nº 1940 is an automatic and hand wound mechanical wristwatch with a quick date setting, stop second device and exhibition back. Each 316L stainless steel watch head measures 45 mm width x 50 mm length x 12.5 mm depth (including lugs) and is tested to 10 ATM (100m / 325ft) water resistance.

Utlising a beautiful combination of meticulously brushed surfaces, it has been elevated further with the use of high contrast two-tone finishes. The machined crown features a bold, deep red anodised finish, consistent with all of our past collections.

The screw down exhibition back, printed with the WT Author mark and uniquely allocated serial number, gives the wearer uninterrupted access to view the inner workings of the intricate mechanical movement. The bespoke watch head is finished with a refined Italian leather handmade strap.

Every watch is built to order with British and imported parts in our UK workshop located in Shropshire. Each watch is guaranteed against any defects in material or workmanship that may occur under normal use for a period of 24 months from the date of purchase. Learn more.

Featuring a green finish applied to a subtle matt dial that brings a high contrast against the accurately painted dial details. Custom, aircraft gauge markings decorate the dial against contrasting markings with stunning luminous infill on the minute / hour hands and indices.

In 1959, Citizen Watch established a movement manufacturing factory in the town of Miyota, Japan.

The caliber Nº 9015 is both an automatic and hand wound mechanical movement, assembled using only parts manufactured at Japanese plants. It is produced in-house by high-speed automatic assembly lines and undergoes strict quality checks.

The balance wheel is produced by human hands. Adjusting the eccentricity and horizontality of the balance spring is the most difficult procedure, and cannot be expressed in numerical form by machinery.

The movement is precise and durable with high impact resistance. It is valued for its craftsmanship, artistry and beauty; all major parts are made of metal to enhance colour and texture. We trust Citizen due to the high quality and stable supply that our products require.

The watch head securely houses the intricacies of the delicately assembled mechanical movement, displaying its complexity through the uninterrupted rear lens. It has been designed to fit perfectly on the wrist within a robust and solid watch head that has been assembled to be put through its paces. The result is a timepiece with a 44 mm diameter, a length of 45 mm width x 50 mm length x 12.5 mm depth (including lugs). We effortlessly combine beautifully brushed surfaces that meet to create a clean aesthetic with incredibly strong properties.

The two-tone aesthetic presented through the contrasting finish is enhanced further by a delicately brushed surface.



The intricately machined screw down exhibition back includes deep, tooled recesses with enamel infill to reflect our established signature “poker chip” aesthetic influenced from our previous watch collections. The component creates a powerful seal that ensures water resistance tested to 100m / 10 ATM.

The exhibition back is fitted with a glass lens and ensures the aviation watch retains its maximum water resistance whilst offering an uninterrupted presentation of the mechanical movement’s inner workings.

The stable construction with precisely defined architecture has been designed and machined to be as beautiful as every other component on the watch. The rear lens is finished with our intricately printed mark and serial code to indicate its allotted number in the limited edition collection.

The crown is placed at the 3 o’clock position with lugs that fall tightly underneath the top component of the watch head, avoiding any discomfort to your wrist.



The sapphire coating offers significantly more scratch resistance vs. traditional glass, plastic or acrylic crystal as well as being extremely strong.



The watch dial is where we can be the most expressive. The Nº 1940 watch comes in six different colour options: Blue, Cream, Green, Black, Phantom and White. Each one carries a unique pattern of meticulously designed hour, minute and second indices. The hour markers utilise a correlation of our signature “tuning fork” indices painted on the dial to compliment the WT Author mark at the 12 position with luminous infill used for the minute / hour hands and indices.



The highly distinctive minute, hour and second hands utilise gloss painted black, white and red finishes. The bold forms have been designed to be easily read and visible against the dial.



Each leather watch strap has been handmade in Britain using oil tanned dyed through Italian cowhide. The rich colour, treated with waxes and oils offers a distressed effect which lightens in colour when folded or turned. The natural grain is left intact to show all the growth marks and unique character, giving a distinctive look with this mellow feeling skin. The strap has been designed and manufactured to fit a 22 mm lug width with an overall thickness of 3 mm and is embossed with the WT Author ‘A’ trademark. Each strap is completed with a brushed stainless steel buckle and finished with rounded, burnished strap edges.



Our packaging has been engineered to be 100% reusable and recyclable, as well as providing a lightweight solution to reduce wasteful distribution. We endeavour to use recycled stock at every possible opportunity. The inherent beauty of this repurposed material is adorned by our own exclusive artwork.

Every watch comes accompanied by the following items:

  • Signed and numbered screen print (limited edition screen print with signature and corresponding number to match the watch’s serial code).
  • Chapter 5 taken from The Book of WT Author (the Nº 1940’s story visualised within a beautifully formatted booklet).

    I have followed W. T. Author watches from the first crowd funding days, I have never been disappointed in the watches produced. I wanted a watch that was different to the run of the mill, didn’t break the bank and was eminently usable. I have a model of every edition and didn’t realise I was a watch collector until I bought the first 1905.
    Support British made goods, buy a quality limited edition watch from W. T. Author today! (but make sure I’ve bought mine before they sell out…)

    There’s something very special about this company which is addictive dont ask me why but the story behind the watches just draws you in and if you ever have the pleasure of meeting the owners you will understand why.

    I got the 1940 green face model as a birthday gift from my wife, it’s an absolutely stunning watch. Ive been wearing it for a few weeks now and it has really settled on the wrist well, the strap is so comfortable.I love the packaging that the watch came in with all the extra items in the box, WTAuthor really do go that extra mile. Can’t wait to own another.

    Came across WTAuthor at Duxford this September whilst perusing the many exhibitor stalls. At a glance I thought it was just another peddler of watches as I walked past. What made me stop was that I didn’t recognise the Brand and when I saw the prices I was I intrigued as opposed to put off.

    There was no hard sell and Sam introduced himself and the story and concept behind the watches. The more I listened the more I felt that was looking at a product that represented or reflected on my personality.

    It was unique, a limited edition offering, built to order with a fascinating storyboard of period designs and a British company. I loved the presentation, the styling, the build quality and I felt Sam was offering a genuine product backed by a design team that believed in their product.

    Sam seemed genuinely interested in spending time answering all my questions knowing there probably wouldn’t be sale there and then which reassured me further. It was like to talking to a friend than a sales person.

    The result was a decision to purchase a 1940 automatic movement online a few weeks later. I keep in touch with Sam via WT Arthur’s FB Page and love the personal touch.

    The watch was delivered beautifully presented with a hand written note which made me feel very valued as a customer which at this time further reinforces the values and customer service of this company.

    Thank you for a great watch and great service to date.

    I stumbled across WT Author at the Bath and West show and i was so impressed with not only the style but also the quality of these pieces, when I looked into their history and read their story i was hooked!!.
    I now have a 13 year plan of my own and have just ordered the latest edition to go with the other 6 in the collection.
    Excellent quality watches , I would recommend to anyone.
    Every watch collection should include a WT Author.
