The Seiko Prospex SPB143J1

The Seiko Prospex SPB143J1 is a modern interpretation of the Japanese manufacturer’s first 62MAS diver’s watch, launched in 1965.

The SPB143J1 diver’s watch with an anthracite gray dial is in the price range of just over a thousand euros in Seiko’s Prospex collection, for which Seiko has offered an exceptional amount of value with its Sharp Edged watch collection as well.

The watch bearing the model name Seiko Elite Prospex Diver’s 1965 Modern Re-Interpretation SPB143J1 is particularly attractive due to its moderate size range of 40.5 millimeters. Combined with a reasonable thickness of 13.2 millimeters for the diver’s watch, as well as a restrained height of 46.5 millimeters from lug-to-lug, the SPB143J1 fits perfectly on even the smallest wrist.

The fit is also emphasized by the well-made steel bracelet. If I have to complain about anything, it is a mechanism that requires the strength and finger dexterity of a diver’s extension that is essentially part of the wristwatch of watches. Some kind of more subtle adjustment mechanism would be a great improvement. Namely, my own wrist swells, especially during the summer, as the day progresses, when an easy way of relaxing would serve its purpose.

The design of the watch represents Seiko’s distinctive DNA, which focuses not only on the dial but also on the design of the watch case. The line of the stainless steel case is curved, making it not only sedentary but also simply beautiful. The surfaces of the case are mostly brushed, which fits the tool-like style of the watch. The bevels on the watch case, on the other hand, are polished, which brings subtle life to the watch and helps to visually connect the three-row steel bracelet – the ends of which are polished – into the shape of the watch.

The SPB143J1’s anthracite-colored dial is sunray finished, giving it a subtle glow. The readability on the dial is excellent, as the heavily snow-massed indices and indicators are large. Elevated indices also stand out beautifully from the dial.

The ensemble is complemented by a curved sapphire crystal that is protected from the inside, through which the dial is comfortable to look at. From this we also get to perhaps the most beautiful detail of the watch, which is the shade of the dial ranging from light gray to almost black, which varies with the light.

Technical features

The Prospex SPB143J1 relies on Seiko’s own 6R35 automatic movement with 70 hours of power reserve. The control feel of the movement is good, except for the small gap in the screw-locking crown. The watch is promised a water resistance of 200 meters and, like all diver watches in the Prospex collection, meets the requirements of the ISO 6425 standard for diver watches.

The watch has a 120-step, counterclockwise steel bezel with a strong Lumibrite snow mass at the 12 o’clock spot. The feel of the bezel is tight, so it does not move unintentionally during normal use.

Summary

The Seiko Prospex SPB143J1 is a low-key diver’s watch that works in any situation. Due to its style, it is a sporty watch for leisure time and due to its technical features, it is also a qualified watch for diving enthusiasts. The watch can also be recommended for a female wrist because of its size and understated style.
