Get your hands on this 2018 Seiko Astron SSH003J1 GPS Solar Dual-Time with calibre 5X53, titanium case and bracelet, ceramic bezel, sapphire crystal and original boxes.

Model history:

The original Seiko Astron, introduced in 1969, was the world’s first commercially available quartz wristwatch. Seiko revived the historic name in 2012 for its GPS Solar collection, combining satellite-controlled time and time-zone adjustment with light-powered quartz technology.

Introduced in late 2018, the 5X generation represented a major technical development for the Astron collection. Its redesigned GPS module allowed Seiko to create what was, at the time of its launch, the smallest and thinnest GPS Solar watch available. The 5X53 movement also introduced faster time-zone adjustment, automatic satellite reception up to twice per day and a time-transfer function for instantly exchanging the indications of the home and local time zones.

This example was manufactured in December 2018, during the introductory period of the 5X series. It corresponds to model SSH003J1, known as SBXC003 in the Japanese market.

Condition:

The watch is presented in very good pre-owned condition and is functioning correctly. Its complex graphite-grey dial is very well preserved, with clean applied hour markers, hands, subdials, date window and printed indications. The dial changes subtly between charcoal, grey and purple-grey tones depending on the lighting. The original sapphire crystal remains clear and scratch-free.

The black ceramic bezel is well preserved, with clearly legible city and time-zone markings. The titanium case displays scratches, small marks and surface wear consistent with previous use, particularly around the polished case edges, crown guards and pushers. The contrasting brushed and polished surfaces remain clearly visible.

The original titanium bracelet and signed Seiko clasp show scratches, scuffs and normal signs of wear. The bracelet remains structurally sound and, together with the watch, accommodates wrists up to approximately 19 cm.

The original protective sticker is still present on the case back. The sticker shows handling and age-related marks, while the engravings beneath and around it remain visible.

The original Seiko Astron inner and outer boxes are included. Please note that the cushion inside the presentation box is not original and has been replaced. The original papers are no longer present.

The movement has not undergone service. However, all functions are operating correctly. The original Seiko Astron inner and outer boxes are included, but the papers are no longer present.


I aim to capture the condition of the watch accurately. Please make sure to review the pictures closely before bidding.
