Until August 4th! "Watch in Style ~ Pop-up Store & Workshop"

　The "Watch in Style ~ Pop-up Store & Workshop" event is being held at the Central Hall on the 1st floor of the main building of Nihonbashi Mitsukoshi Main Store in Nihonbashi, Tokyo, until August 4th, 2026 (Tuesday). Omega, Longines, Rado, Tissot, and Hamilton are participating in this limited-time event, each with their own pop-up store, but Omega, in particular, is expressing a special world view in a large space. This world view follows the campaign that the brand started in June, "Speedmaster, an icon since 1957." The interior is themed around the Speedmaster, which was born as a racing chronograph in 1957 and later earned the title of "Moonwatch" after being carried on the moon landing as official equipment of NASA, and a collection specializing in the Speedmaster is also available. This is an event that Omega fans should definitely visit.

An exhibition that captures the world of the Speedmaster.

"Watch in Style ~ Pop-up Store & Workshop" was held in the central hall where a giant statue of a celestial maiden with sincerity stands. Combined with the eye-catching golden astronaut in the center, I remember noticing a noticeable number of shoppers and tourists being drawn in on the day of my visit.

　As mentioned earlier, the Speedmaster is an Omega chronograph model that was born in 1957. Positioned as a racing chronograph developed for motorsport, it was equipped with airtightness and robustness, and to ensure visibility, the tachymeter scale was set on the stainless steel outer bezel.

The first model, the Speedmaster Ref. CK2915, was released in 1957. The Seamaster 300, released in the same year, served as the basis for its development.

　It was space exploration that brought the Speedmaster, along with the nickname "Moonwatch," to widespread recognition. In October 1962, astronaut Walter Schirra, participating in NASA's Mercury program, wore his own Speedmaster while orbiting the Earth. Then, in 1965, NASA officially adopted the Speedmaster as official equipment, and in 1969, astronaut Buzz Aldrin wore it during his moonwalk on the Apollo 11 mission.

Omega "Speedmaster Moonwatch" Ref. 310.30.42.50.01.001
The current model inherits the "Moonwatch" title. It retains the design elements of the fourth-generation watch carried on the Apollo 11 mission, including the reinforced plastic (Hesalite) crystal and the seahorse medallion on the case back. Manual winding (Cal. 3861). 26 jewels. 21,600 vibrations/hour. Power reserve of approximately 50 hours. Stainless steel case (42mm diameter, 13.54mm thickness). 50m water resistance. 1,166,000 yen (including tax).

　Inspired by the world of the Speedmaster campaign and the idea of connecting the collection's history with current models, the event space immediately catches the eye with its central Golden Astronaut. Perhaps because it's located in the central hall, a high-traffic area, I encountered several instances during my 30-minute visit where shoppers and tourists seemed to casually stop by. Incidentally, this Golden Astronaut is usually only displayed in a limited number of boutiques. The display, which evokes the history of the Speedmaster, was also enjoyable to look at.

With the statue of the celestial maiden at Nihonbashi Mitsukoshi Main Store as a backdrop, displays and videos showcasing the world of Speedmaster watches create an eye-catching event space for shoppers.

The exhibition also featured photographs of the "Gray Side of the Moon," a version of the "Speedmaster Dark Side of the Moon" inspired by the phrase "The moon is essentially gray," left behind by Apollo 8 commander Jim Lovell. The design is accented with patterns reminiscent of the craters on the lunar surface.

The reporters are reflected in the gleaming golden astronaut.

Over 70 models on display. The joy of comparing different Speedmasters.

　This event is more than just a showcase of the Speedmaster's world. More than 70 different Speedmaster models are on display at all times, including some rare models that are rarely seen in Japan.

One of the defining characteristics of the Speedmaster is its wide range of variations, going beyond just the "Moonwatch." These include models based on the "Moonwatch" but with more luxurious dial colors and materials, the "Speedmaster 38mm" with a 38mm diameter case that appeals to both men and women, and the "Speedmaster Pilot" which emphasizes its pilot watch aesthetic. This event truly highlighted the diverse range of models available. In the center of the photo is the "Speedmaster Chronoscope," which features a tachymeter, pulsometer, and telemeter scale.

The "Speedmaster Moonwatch Black White" with its "reverse panda dial," released in January of this year, was also on display. The 18K Moonshine™ gold model was a first for me.

You can also compare the Speedmaster Moonwatch. And in the foreground of this photo is the "FOIS," or "Speedmaster First Omega in Space"...!

　In addition to the Speedmaster itself, replacement NATO straps are also available for purchase. Readers who already own a Speedmaster will likely enjoy both the event and the shopping.

Watch enthusiasts, check out this workshop!

A workshop that will make any watch enthusiast drool, featuring a watch technician who actually works in the customer service department of the Swatch Group demonstrating the disassembly and assembly of an Omega movement...!

　My personal highlight of this event was the workshop. Watchmakers from the Swatch Group demonstrated the disassembly and reassembly of Omega movements. This workshop is held daily. Incidentally, which movement is disassembled and reassembled depends on the watchmaker demonstrating it! During my visit, the Cal. 1152, which was once used in Speedmaster automatic models, and the Cal. 8500 with a Co-Axial escapement were available, and the reporters were shown the intricate details of each part and how carefully even these small parts are finished.

While it's easy to understand when you see it on a monitor, the movement is actually composed of very small parts. It's great to be able to understand these parts, which users normally can't see, with explanations from engineers.

By viewing the perlage decorations and polished bevels applied for aesthetic purposes on a monitor, one can gain a deeper understanding of Omega's expertise as a luxury brand.

A special event that Omega fans won't want to miss.

　I covered the Omega event space at "Watch in Style ~ Pop-up Store & Workshop," which will be held at the Central Hall on the 1st floor of the main building of Nihonbashi Mitsukoshi Main Store until August 4th, 2026 (Tuesday). As I mentioned several times in the article, I strongly felt that this event is a must-see not only for Omega fans but also for watch enthusiasts in general.

　In addition to Omega, watches from Longines, Rado, Tissot, and Hamilton are also on display. Furthermore, there is a watch gallery on the 6th floor of the building. Why not spend a day immersed in watches at Nihonbashi Mitsukoshi Main Store at the start of summer?
