Eva Leube

Eva Leube is an independent watch maker from Australia and specialised in handmade mechanical timepieces. in 2011, her brand made debut at Baselworld jewellery and watch fair by unveiling “Ari”, a unique mechanical timepiece collection.Eva Leube watchImmediately striking are Ari’s strong, clean lines and uninterrupted views of the curvaceous movement, resplendently on display thanks to the adroit use of sapphire crystals on both sides of the case.

The audaciously bowed movement sees the balance placed at the top, its vibrant oscillations providing a mesmerising feast for the eyes. Beneath that is a sub-dial displaying seconds followed by the elegantly simple hours and minutes dial in the centre. All the hands are in traditional heat-blued steel. Further down, “Eva Leube” is hand-engraved on the ratchet wheel. At the bottom of the movement is the small crown wheel, with the crown for winding and time-setting at the bottom of the case.

To allow for a panoramic sapphire window along the entire right side of the case, the crown has been ingeniously moved to the bottom of the movement by creating a new hand-setting mechanism hidden inside the mainplate, travelling from the centre of the watch towards its base.

In most watch movements, the crown wheel, ratchet wheel, click with click spring, escapement and balance all face down towards the back of the watch. For Ari, Eva has turned them all to face up towards the viewer, making the open-face movement even more visually attractive. Not surprisingly, this created considerable challenges and required additional intermediate pinions, a reversed escape wheel and a reworked pallet fork.
Eva Leube Ari watchAri features a screw-in locking crown, which is unusual for a manual winding timepiece. With a standard mainspring and barrel, winding the watch turns the ratchet wheel until the spring is fully wound – then you can wind/turn no more.

Ari, however, features a mainspring with a sliding bridle more usually seen with automatic winding systems. As a result, the timepiece can be fully wound and then turned further still until “Eva Leube”, hand-engraved on the top of the ratchet wheel, is in the right position. The crown can then be screwed in and locked so that the name remains correctly orientated.
Eva Leube Ari mechanical watchWhile the case is light and bright in design, the watch as a whole retains excellent rigidity and strength. The movement is mounted directly to the case back, ensuring that the seemingly light and fine construction is extremely robust.

Biography: Eva Leube
Eva Leube is based in Manly near Sydney, Australia, a long way from where she was born, in Berlin, Germany. In 1995 at Hildesheim in her native country, Eva precociously obtained her Master Watchmaker diploma at the age of 23.

Eva went on to work in a fourth generation family-owned watch company in Lucern, Switzerland before working for Chronos Master Watchmakers in Cape Town, South Africa. During this time she completed a Rolex course in Geneva before eventually moving to Sydney to work for Rolex Australia.
In 2004, she returned to Europe and worked with Ulysse Nardin in Switzerland, followed by two years working with independent watchmaker and master of complications Thomas Prescher. Eva’s time with Prescher was spent building custom timepieces with particularly complex functions such as retrograde time indications and multiple-axis flying tourbillons.

After spending 13 years honing her skills and learning from some of the best in the business, Eva returned to Australia. Following the birth of her son, she set up her own workshop and began turning her vision of a curved watch into a reality. Four years later, Ari was unveiled at Baselworld 2011 to great acclaim.
