The integrated bracelet luxury sports watch has been the most successful category over the past few years. This ongoing trend has driven more and more players into this market, including independent watchmakers. Among these is H. Moser & Cie. with its sleek Streamliner introduced in 2020. The model stands out with a distinct personality breaking away from the countless Royal Oak-inspired watches, an expressive design with fluid lines. The model has been offered with different movements – chronograph, centre second, perpetual calendar, or tourbillon. It now comes in a supremely elegant and thin version with a gradient Grand Feu enamel dial and a new in-house movement, the H. Moser & Cie. Streamliner Small Seconds Micro-Rotor.

Fashioned out of stainless steel, this new streamliner retains its distinctive, smooth, rounded cushion case with no lugs and an integrated bracelet. The proportions have been slightly adapted with tauter, more ergonomic lines. At 39mm, the case is the smallest and thinnest Streamliner so far, which was made possible thanks to the new micro-rotor movement, the HMC 500. The elegant arched profile of the integrated bracelet beautifully extends the case while following the anatomy of the wrist. Its wave-like pattern is highlighted with vertical brush flat surfaces and crisp, polished bevels where one link meets the next. The short links allow for the desired flexibility and, together with the smaller case, enhance comfort. The 3-blade folding clasp is released via a pair of pushers. The water resistance is rated at 120 meters.

The delectable Grand Feu dial adds to the model’s distinctive personality. This original, artistic interpretation of the gradient dial is based on a textured base plate, coloured with three different enamel pigments mixed and applied to create a gradient effect. The dials are fired 12 times in succession to achieve a soft transition between the different tones. As is often the case with Moser, the dial has no logo. The lacquered small second stands out with its concentric motif. Reading off the applied indices are the hour and minute hands with Globolight inserts, a ceramic-based material that contains Super-LumiNova.

As said, a new micro-rotor movement powers the Streamliner Small Seconds, the HMC 500, made in-house, including the hairspring manufactured by Precision Engineering AG, Moser’s sister company. The brand’s CEO Edouard Meylan advises that it was developed to have a thinner calibre, with a winding mechanism that is not over the movement but integrated at its core. It also allows an uncluttered view of the movement, as there’s no oscillating weight rotating over it. The platinum micro-rotor is emblazoned with the brand’s crest. It is mounted on a ball bearing and winds the movement in two directions. The frequency is 3Hz, and the power reserve is 3 days. The partially openworked movement is decorated in characteristic Moser style with double stripes on the bridges and jewels set in chatons.

  1. Only if someone overheard you, that might misunderstand…..

    Wow. Just….wow.

  2. Lovely – I think this is fantastic subtle refinement of the case. the flow from bracelet to watch head just works even better. I noticed that the review sample looks to unique a the the small seconds markings are not aligned correctly. I thought this was maybe, knowing Moser, a potential design choice, but noticed other websites (Hodinkee) showing the markers as aligned. Could you confirm which is ‘correct’?
