The Seiko Astron Novak Djokovic Limited Edition is the SSE174; Seiko’s Spanish regional product page gives the reference as SSE174J1. Seiko says 1,500 pieces were made. The 2018 launch specification pairs GPS Solar calibre 8X53 with a large 46.7 mm titanium case, ceramic bezel and silicone strap.
What is the Seiko Astron SSE174?
The SSE174 is Seiko’s Novak Djokovic Limited Edition in the Astron GPS Solar executive sports series. Seiko’s product page identifies the model as SSE174 and lists the regional reference SSE174J1; those labels are not necessarily competing model identities. Seiko’s March 22, 2018 press release said the watch would be available from September 2018 at selected Seiko outlets worldwide.

What does the 8X53 GPS Solar movement do?
The 8X53 receives GPS signals to adjust the time and time zone automatically. Seiko lists 40-zone world time, dual time, day and date, a perpetual calendar through February 28, 2100, and a daylight-saving-time function.
Additional listed functions include signal acquisition and result indicators, a power-reserve display, power saving, overcharge prevention and automatic hand-position alignment. The stated accuracy of ±15 seconds per month applies when the watch does not receive a GPS signal and is within Seiko’s specified 5°C–35°C temperature range.
What makes the Djokovic edition distinctive?
Seiko’s March 2018 announcement explains the tennis references in the dial and bezel. Four minute markers use “Love,” “15,” “30” and “40,” the familiar tennis scoring sequence. A star at the eight o’clock marker refers to Djokovic being one of eight players to achieve a career Grand Slam.
The bezel highlights UTC codes for Paris, London, New York and Melbourne, the four cities that host the Grand Slam tournaments. These are Seiko’s explanations of the design details.

How much did the SSE174 cost?
There are two dated Seiko price references, which should not be read as the same kind of price. Seiko’s March 2018 press release gave an approximate recommended retail price of €2,700 in Europe. Seiko’s Spanish regional product page displays €2,800 as of October 8, 2026.
Neither figure establishes current stock, a completed sale price or the watch’s present resale value. The regional page’s displayed price may also change.
What to check when comparing or buying one
For a comparison with another Astron, focus on the calibre and GPS Solar generation, dimensions and materials, water resistance, time-zone functions, edition details and the date and region attached to any price. The specifications above identify what Seiko lists for this model, but they do not establish a performance ranking against other Astrons.
If considering a pre-owned SSE174, check that the reference matches the listing and inspect condition, seller terms, return policy and included contents. Seiko’s 2018 announcement named selected outlets worldwide for the launch, but that does not confirm present retailer inventory. The 24 mm lug width is listed; compatibility with any particular replacement strap is not established here.
