ASTRON GPS SOLAR DUAL-TIME CHRONOGRAPH SSH177

Astron GPS Solar Dual-Time Chronograph. Extending the legacy of the Seiko Astron, the world’s first commercially available quartz watch, today’s Astron is designed for a new generation of leaders to break through to a new future with excellence in both innovation and style. Combining solid tailoring with the highest degree of accuracy possible in a wristwatch, this exceptional timepiece is equipped with Seiko’s 5X83 caliber, offering both high-speed GPS dual time and time zone adjustment to 39 time zones and a chronograph function that measures elapsed time in 1/20th second increments. The precision watch also features an AM/PM indicator, daylight saving time function, power save function, perpetual day/date calendar correct to the year 2100, and a time transfer function that allows the user to switch the main time and dual time indications with the push of a button, all powered by light energy with no battery change required. Framed by a titanium bezel with a brilliant black sapphire insert, and topped with dual curved sapphire crystal with super-clear coating, the silver-gray patterned dial displays a distinct texture, made possible by improved charging efficiency of the solar cell, providing an outstanding contrast to the subdials. In addition to the four subdials, laid out vertically for a sporty look, the dial includes a date calendar and LumiBrite hands and markers for enhanced visibility in low-light conditions. Crafted of light and durable titanium with super-hard coating, this superb timepiece has a contemporary feel thanks to the sleek lines, slim profile, and the compact and angular design that seamlessly flows from the case to the bracelet and includes a secure screwdown caseback and tri-fold push button release clasp with Smart Adjuster function. 10 bar, 100M Water Resistant

I can’t say enough wonderful things about my experience, especially thanks to Sterling at Dejaun Jewelers. I had been searching everywhere for the limited-stock Seiko “Pepsi” SSK047 — it was sold out almost instantly and nearly impossible to find. This watch was a gift for a close friend who never asks for much, and this was the one thing he truly wanted. I was determined to find it for him. When I reached out, Sterling immediately reassured me that they had a few in stock. His communication was warm, clear, and incredibly patient as he confirmed everything I needed to know. He understood how meaningful this gift was, and within just a few hours of placing the order, he surprised me by sending the UPS tracking number. That level of responsiveness and care is rare these days. Sterling turned what could’ve been a stressful search into a smooth, heartwarming experience. Thanks to him, I was able to secure a special, hard-to-find watch for someone who truly deserves it. I’m deeply grateful and highly recommend this team. If you’re looking for honesty, commitment, and exceptional service, Dejaun Jewelers is the place.

I had an amazing experience purchasing our rings here, and I want to give a special shout-out to Sterling. From the very beginning, he made the entire process smooth, stress-free, and enjoyable. He was incredibly patient, knowledgeable, and responsive to every question I had — even sending updates along the way so I always knew what was happening with the order. When the ring arrived, he shipped it immediately and followed up with tracking information right away. It’s rare to find someone who genuinely cares about customer satisfaction the way Sterling does. His professionalism and kindness made us feel taken care of throughout the whole process. If you’re looking for great quality jewelry and outstanding service, especially with someone who will go above and beyond for you, ask for Sterling. Highly recommend
