The K4 is inspired by the hydroplane that delivered Sir Malcolm Campbell to his fastest speed ever achieved on water. Powered by a Rolls-Royce R 37-litre, 12-cylinder supercharged engine delivering a staggering 2,800 horsepower, the K4 would surge towards its 141.74mph speed record on Coniston Water on 19th August 1939.

The Coniston Automatic Collection has been designed in collaboration with the Campbell Family Heritage Trust, with donations from every sale going to support and celebrate the Campbell family legacy.


All our watches are made in sequentially numbered small batches - the Coniston Auto K4 is a limited run of 300 pieces.


On the 19th August 1939, Sir Malcolm Campbell powered his hydroplane Blue Bird K4 to 141.74 mph across Coniston Water, capturing the world record.

The Devil's In The Detail

The K4, with its white dial, grey accents and deep blue outer ring takes inspiration from this incredible engineering marvel, and with the little pop of yellow, hints at what inspiration the K4, Sir Malcolm and the thrill of speed had on Donald’s water speed record aspirations.

We’ve improved the contrast of the chapter ring’s minute track, added in some metallic texture and a subtle grey pattern around the central plateau - all in the mission to delicately adapt and enhance the original design. The dynamic depth is retained through the use of a multi-part dial construction and applied indices extending outwards over the moat of lume.

The hands float above the white surface, their skeletonised structure combining to form one segmented hand, with the polished running seconds hand now featuring a counterweight.


Iteration. Improvement. The Coniston Automatic dial has been improved in almost every facet, subtly, deftly, to bring a greater sense of theatre - polished chamfers, two-tone bezel and central plateau, brushed textures and polished batons do the job.


Knurling is a mechanical texture deployed in motorsport on important switchgear to make sure it's a positive experience. We've used that as inspiration for the bezel outer in a nod to the Coniston's motorsport inspiration.

Flowing Design

Re-designed completely for the Automatic era, the Coniston's case features a three-phase sectioning - the top has the knurled ring, followed by a flowing, beautifully formed light-catching strip leading smoothly into the lugs, and a final aggressively angled case-back, to nestle into the wrist.


For this new and improved Coniston we've turned to an automatic movement - the Miyota 8N24. It's a direct descendent of the 8N33 that featured in our manual Coniston, and features the same beautiful skeletonised structure, but with improved functionality; hacking seconds and hand-winding capabilities.


Continuing the iconic luminous capabilities of its predecessor, the Coniston Auto features a moat of lume around the periphery of the dial, and the same segmented hands, overlapping to create one glowing superhand.

Excellent in every respect. Bought as a present. Wish I had one myself.

Really good looking watch. It's a Marloe so the quality is superb. I can't think of anyone else offering this much attention to detail and quality for the price.

I recently purchased the K4 and have enjoyed it from the first moment of opening the box. The watch itself is beautifully constructed with its dual texture casement and sapphire crystal.

Iterate. Improve.

The Coniston always was a handsome fellow, with incredible dynamism of dial design and beautifully bespoke features - hands that resemble structural cross-sections, a glowing moat of illumination and striking refractions from the domed crystal.

We’ve had a lot of great feedback over the years following the launch of the Coniston, with much of the positivity focused on the dial and hand set, as well as the magically deep dial design that your eye can get lost in.

It would have been sacrilege to ignore these elements when reconsidering the design for Coniston Auto, so we’ve tweaked them ever so slightly, with delicacy and perspective, to make them just that wee bit more resolved.
