For sale is a Seiko Astron SBXY055 Approximate Measurements:  Case: 43 Case  Lug to Lug: 48 mm Thickness: 12 mm Lug Width: Integrated I bought this watch from Seiya Japan and it comes with the box, papers, and all extra links. The watch is titanium and coated in DLC and is in very good shape. There are no major marks or scratches case, crystal, or ceramic bezel. This is an LE with number 407 of 500 total made.  This is a radio-sync watch which means it will set itself using a radio broadcast overnight. In the United States that broadcast station is in Colorado so the closer you live to Colorado the better, however, I live in California and receive a signal about every other night depending on where the watch is in the house.  This watch has a very sneaky quick adjust in the clasp. If you hold down the twin trigger it has a few positions it can quick adjust to.  Finally, this watch is also dual time, and you can adjust both the main hands and the sub dial at 6 to separate time zones. You are definitely going to want to read the included instructions, the watch does not operate traditionally through the crown, but rather uses the buttons. Once you get the hang of it you can adjust it quickly and easily! $850 obo shipped via USPS Priority.  CONUS only, payment via Paypal F&F or G&S (+ fees) for buyers with excellent feedback.  No trades please, thank you for looking :)
