Seiko Presage SSA468J1 Watch - Japanese Garden - Automatic Open Heart

Seiko Presage SSA468J1 Watch

The Seiko Presage SSA468J1 belongs to the Japanese Garden series of Presage, the line that Seiko dedicates to bringing landscapes and motifs from Japanese culture to the dial. In this reference, the starting point is the Karesansui, the dry garden of Kyoto where raked gravel suggests water and movement. The dial reproduces that pattern in relief on a gold background, and combines it with an Open Heart aperture at 9 that reveals the movement. The idea it represents is not that of a watch that hides its mechanics, but that of one that integrates them into the landscape of the dial.

The movement is the 4R39 caliber, automatic with manual winding, 24 jewels and a power reserve of approximately 41 hours. It incorporates a 24-hour hand and hacking seconds. The steel case measures 41.8 mm in diameter, 12.5 mm in thickness and 48.4 mm lug-to-lug, with 20 mm lug width. The crystal is double-curved sapphire and the case back is see-through and screw-down. Water resistance is 3 ATM (splash resistant). The gold steel bracelet has a 20 mm width and a deployant clasp with pusher. The weight is 130 grams.

The dial is divided into two zones that don't share the same treatment. On the left, the Open Heart at 9 and the 24-hour subdial at 11 reveal the movement and add a second time reference. On the right, the Karesansui pattern occupies the surface with grooves that generate shadows and change in intensity depending on the angle. That division is the feature that defines the watch: it's not a uniform dial with a window, but two aesthetics that coexist on the same surface. If a shirt cuff covers the lower part, what remains in view is the textured zone; if worn with the wrist uncovered, the Open Heart and the subdial come into the field of vision. The watch doesn't read the same in both situations, and that is precisely its particularity.

Why choose this watch?

4R39 caliber with 24-hour hand and hacking seconds

The 4R39 isn't a time-only automatic. It adds a 24-hour hand for a second time reference and hacking seconds, the latter allowing you to set the time to the second. The 41-hour power reserve covers a night and a day without wearing it.

Split dial: Open Heart at 9 and Karesansui on the right

The left half shows the movement's balance wheel and the 24h subdial; the right half is occupied by the raked gravel pattern. It's not a homogeneous dial with a window: they are two different treatments that force you to look at the watch twice.

41.8 mm with gold steel bracelet: the gold variant of Japanese Garden

The 41.8 mm keep the watch in dress-watch territory without falling into a small format. The gold steel bracelet closes the chromatic continuity of the case and dial, which in this Japanese Garden variant represent the brilliance of old Kyoto. The deployant clasp with pusher adjusts the bracelet to the wrist without tools.

Frequently asked questions

Is the 24-hour subdial used for a second time zone?

No. The 24-hour subdial at 11 indicates the time in 24-hour format within the same time zone as the watch, it is not an independent second time zone. It is adjusted together with the main time via the crown and cannot be offset separately.

Is the dial texture an engraving or a relief?

It's a deep relief pattern, not a flat print. Seiko describes the effect as grooves that generate shadows, so that the intensity of the gold varies depending on the angle of the dial relative to the light.
