The most complicated H. Moser & Cie. sports watch to date, the Streamliner Concept Minute Repeater Tourbillon Blue Enamel is derived from the unique Streamliner Pandamonium created in collaboration with MB&F. The new Streamliner retains both the minute repeater and tourbillon, but without the panda figure and the oversized balance wheel.

In typical Moser “concept” style, the blue grand feu enamel dial is free of any markings and finished with a fumè gradient effect that darkens towards the periphery. Also found in the Endeavour, the movement was developed in collaboration with specialist Manufacture Hautes Complications (MHC).

Initial thoughts

Since Moser released the Streamliner four years ago, the sports watch has become the brand’s bestseller – unsurprisingly given the popularity of the integrated-bracelet-sports-watch category in general. The new repeater-tourbillon fills in a gap in the Streamliner range, which is to say a top-of-the-line, flagship complication.

Both minute repeater and flying tourbillon are visible on the dial

If you like the Streamliner design, as I do, the new repeater-tourbillon is a handsome watch. The addition of the visible mechanisms on the dial add greater detail and depth to the visuals, while the fired enamel dial is a nice tough, though a fragile enamel dial is somewhat paradoxical in a sports watch.

The repeater-tourbillon is similar in dimensions to the Streamliner chronograph, a good size for a sports watch of this design.

The only downside of the watch is a broader one, which is the frequent iterations and limited edition variants of the Streamliner. Admittedly this is not unique to Moser but common across luxury-sports watches in general, but at the price level of the repeater-tourbillon it should be “very rare”.

Striking looks

Though the dial is free of any branding, it is recognisable as Moser thanks to the V-shaped tourbillon bridge that is the brand’s signature.

The grand feu enamel dial is in translucent “Aqua blue” that reveals the hammered surface of the solid gold dial base. The translucent enamel has a graduated finish that darkens towards the edges, which was achieved with four different shades of blue enamel.

The enamel dial has a gradient effect, with lighter in the centre and darker towards the periphery

Visible around the enamel dial, the gongs are curved outwards to clear the flying tourbillon, while the mirror-polished hammers sit at 10 o’clock.

While the new Streamliner stays faithful to the model’s design, the construction has been subtly reworked to accommodate the complications. For example, the interior of the case was hollowed out to amplify the repeater’s chimes.

More notably, the case is water resistant to 50 m, which is unusual for a repeater given the difficulty of waterproofing the slide mechanism.

Built for wearability, the case is 42.3 mm in diameter and 14.4 mm thick (including the domed sapphire crystal)

The watch is equipped with the hand-wound HMC 905 that was originally developed in collaboration with MHC but now made in-house by Moser after MHC went bust.

It’s visible through the open back and sports a high contrast finish of dark grey ruthenium-coated bridges with gilded wheels and a gold chaton for the pivot jewel of the barrel.
