Marking the world’s first consumer quartz watch, the original Seiko Astron is the watch that launched the quartz crisis or quartz revolution, depending on your perspective. In recent years, Seiko revived this legendary name to mark the world’s first Solar GPS watch. Time signals received from the atomic clocks aboard GPS satellites adjust the time and time zone in mere seconds. This model, the Seiko Astron SSJ007 or SBXD007, marked the first time Seiko fit Astron technology inside an extremely wearable 39mm case. Features include all Titanium construction, a ceramic bezel, 200m WR, AR coated sapphire crystal, textured dial, Lumibrite, GPS, Solar, and adjustable clasp. Also, the seconds hand hits every marker bang on. Price: $1,200 shipped CONUS. Zelle preferred, PayPal F&F for those with transactions here. Excellent condition.
