We like the ethos behind Undone watches here at WRUK. They offer a “Subway sandwich” level of customisation and some strong base designs. The Undone Type XX is their latest model – an aviation chronograph.

Introducing the Undone Type XX

Aviation chronographs are always popular, and the Undone Type XX brings with it the possibility to customise the design of a watch to your liking. It is based on a vintage design: The original Type XX was a pioneering flight instrument used by the French Air Force and Navy aviators in the 1950s. The Type XX brings it bang up to date with a modern movement and the ability to change the colours and styling.


The watch features the popular Seiko VK-64 “meca quartz” chronograph movement. It has the accuracy of a quartz watch, no ticking second hand (there is a 24-hour indicator at 3’O clock and elapsed minutes at ( O’clock) but it also has a 1/5 second sweeping second hand for accurate timing. It’s popular with microbrands as an affordable and desirable choice for low-cost chronographs.

The Type XX is made from 316L stainless steel, and weighs in at 52 grams. If you’ve already got an Undone watch, you may recognise the case: the Undone Type XX is built on the chassis of their best-selling Urban range. That means a 41.5mm diameter and 12.5mm thickness. Lug-to-lug length is 48.5mm and strap width is 20mm. A unique feature is the aviator-style “onion” crown, which gives the design a real vintage kick. We’ve not seen this model, but it shares many components with the Urban Tropical which got the thumbs up in our review.

Buy an Undone Type XX

At £235, we think this new Undone design represents excellent value for money, especially given the level of customisation on offer and the regular availability of discount codes. It’s available direct from Undone’s website. 

You’re best off buying your UNDONE watch direct from the manufacturer, or else you will not get to play with the superb configurator and customise it to your exact specifications. Click here to view the collection and customise your watch.
