THE NEW JUNGHANS SPEKTRUM MEGA SOLAR SHOWS THE CORRECT TIME ALL BY ITSELF.
Some may find it inconvenient, but fans of Junghans' radio-controlled watches take it in stride. For 45 years now, we’ve adjusted to the seasonal time changes each spring and fall (“spring ahead, fall back”). And soon, on the night before the last Sunday in October (October 26), we’ll gain an extra hour as the clocks fall back once more. That’s when a Junghans radio-controlled timepiece like the new Spektrum MEGA Solar truly shines—automatically adjusting the time with ease by receiving a standardised radio signal.
The Spektrum MEGA Solar is both highly precise and energy-efficient. Equipped with advanced radio technology and modern energy management, it harnesses the power of the sun through a glass solar cell that drives its accurate, multi-frequency radio-controlled movement. Like every Junghans timepiece, this sports watch combines cutting-edge innovation with the brand’s hallmark reliability and contemporary design.
Robust and Strong
The Spektrum MEGA Solar stands out with its bold, 41.6-millimeter case crafted from cool stainless steel. Its matte black ceramic bezel not only adds a modern design touch but also provides practical protection for the case top with its exceptional scratch resistance—further reinforced by a durable sapphire crystal. These elements safeguard the integrated solar cell, which powers the watch’s clear, easy-to-read display. Distinctive hour markers with environmentally friendly luminous material ensure visibility, even in the dark.
In addition to the time, a large LCD display presents the date. Beneath the dial lies the true heart of the watch: a solar collector that converts sunlight into electrical energy, keeping the battery charged. If stored away (though there’s hardly a reason to), the movement automatically enters sleep mode after 72 hours and can retain power for more than a year and a half without additional light exposure. When active, the high-precision, multi-frequency radio-controlled solar movement offers an impressive 21-month power reserve.
Suitable for Everyday Use and Comfort
Designed for daily wear, the Spektrum MEGA Solar combines durability with comfort. Its water resistance of 10 bar (100 meters) makes it perfectly suited for swimming and outdoor adventures alike. The stylish, low-maintenance synthetic rubber strap enhances both its practicality and wearing comfort. Whether in summer or winter, the Spektrum MEGA Solar is always the right choice—modern, dependable, and effortlessly versatile.
