In just a few short years since making its debut, the H. Moser & Cie. Streamliner has established its own unique identity among the various integrated bracelet sports watches, and it has become one of the cornerstone offerings in Moser’s catalog. With that in mind, up until this point in time, the Streamliner has only ever been offered on a metal bracelet, regardless of the specific model or the materials used in its construction. However, as its latest new release for 2023, Moser has separated the Streamliner from its signature integrated bracelet and created a new boutique-exclusive version of its flyback chronograph. Crafted from red gold and featuring a green dial with a black rubber strap, the new H. Moser & Cie. Streamliner Flyback Chronograph Automatic Boutique Edition offers a unique take on the brand’s fan-favorite sports model, and it will only be available from its dedicated retail spaces and online sales platform. 

Previously, the chronograph version of the Streamliner was only available in stainless steel, although the new H. Moser & Cie. Streamliner Flyback Chronograph Automatic Boutique Edition (ref. ref. 6907-0400) features its 42.3mm-wide by 14.2mm-thick cushion-shaped case crafted from solid 5N red gold. Beyond the update in materials, the rest of the case remains unchanged, and it features a pair of oblong chronograph pushers at 10 o’clock and 2 o’clock, along with a signed screw-down crown at the 4 o’clock location. A slightly domed sapphire crystal sits above the dial, while a flat sapphire crystal is fitted to the screw-on display caseback, and since the Streamliner Flyback Chronograph features a dynamic water resistance of 120 meters, its two pushers can be fully operated while underwater. 

Despite being incredibly practical and a feature that I personally believe should be more-or-less obligatory on all dive watches that are equipped with chronograph complications, dynamic water resistance isn’t actually all that common, and I don’t really think anyone would have held it against Moser if the pushers on the Streamliner were not able to be operated while the watch is submerged — especially not on this solid gold execution of the model. However, a user-friendly approach is characteristic of many Moser designs (its fool-proof perpetual calendar movement that cannot be damaged by improper setting is also a good example of this), and I personally find it a bit amusing that this solid gold flyback chronograph can be operated at depth, while many diver’s chronographs with burly cases and downright excessive depth ratings cannot.

The dial fitted to the new H. Moser & Cie. Streamliner Flyback Chronograph Automatic Boutique Edition follows the same overall design and layout as previous versions, although it now appears in the brand’s “Matrix Green” color that first appeared on the time-only version of the model. Just like previous executions of the Streamliner Flyback Chronograph, the new green dial features a sunburst finish with a fumé effect that darkens towards the outer edge, while a tachymeter scale sits along the outer perimeter of the checkerboard-style minute track. Other than being finished with 5N red gold to match the case, the hands offer the same shape and style as what can be found on the stainless steel models, complete with their Globolight luminous inserts, while the large applied “60” marker has also been carried over from the stainless steel chronograph models (now finished in 5N red gold to match the case), with the H. Moser & Cie. name subtly sitting below it in transparent lacquer.

Aside from the updated case material, arguably the single biggest update to accompany the new H. Moser & Cie. Streamliner Flyback Chronograph Automatic Boutique Edition is the fact that rather than being fitted with a matching red gold bracelet, the ends of the case flow into a black textured rubber strap. The inside of the strap features titanium inserts for added durability, while the ends close together with a three-blade folding clasp that is crafted from 5N red gold to match the case and engraved with the brand’s logo. While I’m sure there are some people who feel that the Streamliner’s unique integrated bracelet is a core component of the model’s identity, it can also be a bit of a polarizing style, and the decision to bring the Streamliner into the world of straps expands the options for the brand’s sports watch collection quite a bit. Not only does a strap help keep the price down for precious metal models, but it also opens up the doors to different colors and materials, and I could easily see straps playing an increasing role in Moser’s Streamliner collection at some point in the future.

Powering the new H. Moser & Cie. Streamliner Flyback Chronograph Automatic Boutique Edition is the Caliber HMC 907 automatic chronograph movement, which is essentially the same caliber that can be found inside previous versions but with slightly different finishing. The 434-component movement features a column wheel-operated design and it runs at a frequency of 21,600vph (3 Hz) with a power reserve of approximately 72 hours; however, it also features its automatic winding assembly on the dial-side of the movement, which allows for an unobstructed view of the chronograph works through the sapphire display window in its caseback. Additionally, despite being a 60-minute flyback chronograph, the Cal. HMC 907 offers an entirely centrally-mounted hand setup, meaning that the dial of the Streamliner Flyback Chronograph doesn’t have any sub-dials or registers. Instead, a pair of additional centrally mounted hands tracks the elapsed minutes and seconds for the chronograph, while a running seconds indicator for the time has been omitted entirely, and this allows the H. Moser & Cie. Streamliner Flyback Chronograph to offer an ultra-clean and minimal display.

While a solid gold flyback chronograph is never exactly going to be an inexpensive timepiece, not having it fitted with a matching gold integrated bracelet does go a long way towards helping keep the cost down, and the new H. Moser & Cie. Streamliner Flyback Chronograph Automatic Boutique Edition (ref. ref. 6907-0400) is accompanied by an official retail price of $66,000 USD. Additionally, rather than being a limited edition where production is capped at a specific number of examples, this new model is a boutique exclusive version, which means that it can only be purchased at Moser’s own dedicated retail spaces and from its online sales platform. Separating the Streamliner from its signature integrated bracelet is a big step for Moser’s popular sports watch collection, although many of the world’s most famous integrated bracelet models also have strap-equipped siblings, and I wouldn’t be surprised to see straps start to play a larger role in the Streamliner collection over the course of the next several years.
