Extremely rare watch of superlatives!
A high-quality Japanese premium chronograph from Epson 's exclusive TRUME line, positioned as a top brand above Seiko and Orient. The MB52-4AC0 model presented here combines state-of-the-art technology with exquisite craftsmanship and exceptional material quality.
The striking case is made of ceramic and stainless steel with a bronze coating and houses the highly precise, solar-powered, quartz-regulated Epson satellite synchronization movement (Cal. TL1) . This movement automatically connects to GPS satellites and corrects the time and date worldwide.
The watch offers numerous functions: barometric pressure gauge, altimeter, compass, world time (UTC scale on the bezel), daylight indicator (DST), battery indicator (Light Charge), and dual time display. The dial is deep blue with applied indices, gold-tone hands, and a high-contrast UTC scale.
The TL1 draws its power from integrated solar technology in the dial: light is converted into electricity and stored in a rechargeable battery. Thanks to the "Light Charge" indicator, you can keep track of the charge level – battery changes are no longer necessary.
The item is in unworn and almost new condition , including original box, papers and original leather strap (unworn).

Background on the TRUME brand
TRUME ( トゥルーム) wurde 2017 von Epson (dem Mutterkonzern von Seiko und Orient) gegründet, um modernste Präzisionstechnik mit luxuriösem Design zu verbinden. Die Marke nutzt Technologien aus der Luftfahrt und Satellitenkommunikation und richtet sich an anspruchsvolle Sammler, die japanische Ingenieurskunst in Reinform suchen.
Each TRUME model is manufactured in Japan in small batches, with a high proportion of hand-tested components. The TL1 series is the brand's flagship and embodies Epson's expertise in high-end GPS and sensor systems .
The bronze variant ( MB52-4AC0 ) is one of the rarest versions of this series, especially outside of Japan – even on the Japanese secondary market, only a few examples appear.
Market and collector valuation
· Rarity level: very high – hardly available on international platforms
· Condition: almost like new, complete with box and papers
· Technology: High-end GPS/sensor unit (comparable to Citizen F900 or Seiko Astron)
· Design & workmanship: Top class, made in Japan
Briefly explained: GPS, solar power, altimeter & barometer
The TRUME TL1 uses the GPS signal (“Satellite Link”) to automatically synchronize time and date with satellites – at the touch of a button and worldwide, including time zone adjustment.
The "Light Charge" technology is a solar system: the movement is charged by light shining on the dial. Daylight provides particularly fast charging, while normal room light charges more slowly. As the energy level drops, additional functions are first restricted before the watch stops completely.
The altimeter (altitude gauge) and barometer (air pressure gauge) make this watch a true outdoor tool. The current altitude and air pressure can be displayed and calibrated if necessary – practical for orientation in the mountains or for assessing weather trends.
