Introducing the Jaeger-LeCoultre Reverso Vincent van Gogh Miniature Enamel

Van Gogh is immortalised in miniature enamel on the Jaeger-LeCoultre Reverso à Eclipse limited edition.

The work on of troubled Dutch Post-Impressionist returns to Jaeger-LeCoultre Reverso wristwatch with the second Vincent van Gogh limited edition. Equipped with a rolling shutter that slides open to reveal the miniature painting on the dial, the Reverso à Eclipse is the perfect canvas for van Gogh’s work.

While the first van Gogh Reverso depicted one of the famous Sunflowers paintings, the new model features a self-portrait. Van Gogh’s Self-Portrait as a Painter, completed in 1888, is reproduced in hand-painted miniature enamel, a technique often used to decorate the Reverso. Jaeger-LeCoultre is one of the few brands with an in-house team of miniature enamellers.

The case of the watch is platinum, with a slim roller located at one o’clock to open and close the shutters. Inside is the hand-wound calibre 849, a round movement most frequently found inside the Master Ultra-Thin.

Only four will be produced and sold only at Jaeger-LeCoultre’s Amsterdam boutique. The price is €101,000 excluding taxes.

Man 3D Prints His Own Working, Triple Axis Tourbillon

Introducing the Clockwork by Adam Wrigley, a working tri-axial tourbillon made with 3D printed plastic parts - which you can build at home too.

American designer and engineer Adam Wrigley conceived a triple axis tourbillon, having been inspired by Vianney Halter’s Deep Space Tourbillon. Made to be hung on a wall as a kinetic sculpture, Wrigley’s creation is made of 99 parts, with 34 of them being 3D printed. Not only does the tourbillon work, it can be regulated by adjusting the screws on the balance wheel. Here it is in action:

The tourbillon is a complicated mechanism, requiring bearings, barbell plates and fishing line to complete. Here’s Wrigley’s video showing how it’s put together.

Wrigley has generously made the files for the triple axis tourbillon available on 3D printing community site Thingiverse, so if you have the right equipment and dexterity, you can do it at home. All the necessary materials can be purchased via Amazon links on his Thingiverse page.

Hands-On with the Montblanc 4810 TwinFly Chronograph 110 Years Edition

A chronograph with second time zone function, the 4810 TwinFly Chronograph has an in-house movement and mid-range price tag.

Montblanc‘s current strategy when it comes to watches is to offer as much as possible for relatively affordable money, especially compared to the competition. Named after the height in feet of the Mont Blanc peak in the Alps, the 4810 collection unveiled at SIHH 2016 exemplifies this, offering elaborately designed dials and complicated movements.

The 4810 TwinFly Chronograph 110 Years Edition sits in the middle of the collection price-wise, a step up from the basic watches but less pricey than the top of the line tourbillon. And it’s arguably the most interesting, being a flyback chronograph with a second time zone and date, and powered by the in-house MB LL100.1.

A fancy chronograph 

Not a new movement, having been launched with the TimeWalker TwinFly five years ago, the MB LL100.1 is nonetheless interesting. It has the unusual feature of having both the elapsed seconds and minutes of the chronograph on the same axis as the hour and minute hands, a feature historically associated with military chronographs to improve legibility. That explains the numerous hands, five of them in fact, in the centre of the dial.

That configuration should make the dial less busy, since it eliminates the need for chronograph registers, but the fancy design of the dial reverses that somewhat. The dial is elaborately styled to give it an expensive look, with prominent guilloche and gold hour markers.

The second time zone is indicated by the short blued hand in the centre, read in conjunction with the sub-dial at 12 o’clock to distinguish between day and night. Constant seconds and the date are at six o’clock, with an extra-wide aperture for the date that shows not just the current day, but the date before and after.

Devil’s in the details

Though it is heavily decorated – the wavy guilloche is actually the Montblanc star logo in progressively larger repetition – the dial is simply made, being a single, stamped piece. Though they resemble applied markers, the hour indicators are actually part of the dial, produced via stamping. This is a smart and cost efficient way of making an attractively detailed dial.

The movement inside is Montblanc’s own calibre MB LL100.1, an automatic, integrated chronograph movement with a useful three-day power reserve. The “LL” prefix is short for Le Locle, the town where Montblanc’s factory is located.

Montblanc 4810 TwinFly Chronograph 110 Years 7

A large movement, the same thickness and a bit wider than the common Valjoux 7750, the MB LL100.1 has been dressed up with decorative finishing. As with many watches in this price segment, the finishing is basic and done by machine, but nonetheless visually attractive on casual examination.

Bridges are finished with striping and screws are blued, with most of the mechanics below hidden. It’s worth pointing out that the lettering on the movement bridges is printed rather than engraved, making it less appealing.

The watch is quite large, being 43mm in diameter and almost 15mm high, while the white dial and narrow bezel accentuate the perceived size. The case is relatively simple, with a polished finish on all surfaces and rounded edges.

Whether or not the 4810 TwinFly is a good buy depends on the definition of value for money – as much as possible but executed in a basic manner, or as little as possible but done expensively. In fact, it brings to mind the Montblanc Heritage Chronometrie chronograph with annual calendar, another watch that does a lot for relatively less money.

Price and availability 

Limited to 1110 pieces, the 4810 TwinFly Chronograph 110 years Edition is priced at €6900 or S$10,800, equal to about US$7600, and will be available starting in the third quarter of 2016.
