The Seiko Quartz Chronograph (Ref. SKS425 / SKS425P1) is a men’s chronograph from the 2010s that interprets the Japanese brand’s accessible sports segment through a distinctive combination of two-tone aesthetics and analog quartz timing. Its character comes from the interplay of an information-rich anthracite dial, gold-tone details, and a sufficiently refined design that sets it apart from chronographs with a more strictly instrumental appearance.
The three-register configuration is one of the model’s defining elements and complements a design aimed at those looking for a versatile sports watch that is straightforward to use and has a strong visual presence. It is a proposition focused on practical functionality without sacrificing a more refined aesthetic language compared with all-steel configurations.
Design
The anthracite grey dial forms the visual centerpiece of the watch. Its sunray finish reacts to light by shifting from very dark tones to more pronounced metallic reflections, creating depth without relying on elaborate decoration. Against this background, the gold-tone elements stand out: applied indices, hands, sub-dial borders, and peripheral graduations create a strong contrast and visually connect the dial with the two-tone accents found throughout the rest of the watch.
The arrangement of the three registers creates a deliberately dynamic composition. The upper counter occupies the vertical axis, while the other two are positioned across the lower half and left side. The date window at 3 o’clock breaks the symmetry and sits alongside the Seiko signature and the inscriptions on the dial. The peripheral minute track uses slender segments and numerals, adding a technical character without making the overall layout excessively busy.
The main hands, sharp and clearly defined, interact with the elongated indices to emphasize the radial structure of the dial. The bracelet completes the aesthetic identity through silver-tone surfaces crossed by gold-tone central elements. The result clearly belongs to the sport-elegant language of its era: more decorative than an all-steel chronograph, yet sufficiently balanced to retain a distinct watchmaking identity without drifting into the territory of a simple fashion watch.
Case & Construction
The case is made of stainless steel and measures approximately 43-44 mm in diameter, with a thickness of around 11 mm. The lug-to-lug distance is approximately 48 mm, while the lug width measures 20 mm. The proportions therefore favor a substantial width while keeping the vertical profile under control.
The structure combines brushed surfaces with polished areas and is completed by a fixed steel bezel. On the right side are the crown and the two pushers dedicated to operating the chronograph. The dial is protected by a Hardlex crystal, a solution typical of many Seiko watches in this market segment and consistent with the model’s practical positioning.
The stated water resistance reaches 100 meters / 330 feet, equivalent to 10 ATM. Overall, the construction follows a conventional sports-watch approach, prioritizing robustness and structural simplicity over the use of more sophisticated materials.
Movement
The engine is the Seiko Caliber 4T57, a Japanese-made quartz movement developed to manage a multi-register analog chronograph architecture. Its configuration separates standard timekeeping indications from those used during timing operations while retaining fully electronic control of the different hands.
Power is supplied by a Seiko SR920SW battery, with an approximate lifespan of 2 years. Frequent use of the chronograph affects energy consumption because additional indications are activated during timing compared with the watch’s normal operation.
From an ownership perspective, the caliber prioritizes precision, immediacy, and limited routine maintenance. It does not seek the mechanical engagement of an automatic movement, but instead provides a solution consistent with the watch’s intended purpose: a chronograph designed for regular use, in which functional complexity remains accessible without the maintenance requirements typically associated with a mechanical chronograph movement.
Functions & Complications
Standard timekeeping includes hours, minutes, and small continuous seconds. The chronograph section instead uses a central hand dedicated to seconds, a 1/10-second indication, and a counter capable of recording intervals of up to 60 minutes. The separation of these indications makes it easy to distinguish current time from measured elapsed time.
The system also supports a split-time function for measuring intermediate times, expanding its capabilities beyond a chronograph limited to the basic operations of starting, stopping, and resetting. The two side pushers control the timing operations, while the window positioned at 3 o’clock provides the date indication. There are no additional complications: the overall configuration remains focused on measuring short time intervals and providing the everyday practicality of a date display.
Performance
On the wrist, the chronograph has a strong presence with a contemporary character. The case occupies a substantial amount of wrist space, but its relatively restrained profile prevents it from feeling excessively bulky and makes it easier to wear under cuffs that are not too tight. The lugs keep the silhouette reasonably compact, avoiding any unnecessary extension of the watch’s horizontal footprint.
The metal bracelet distributes the weight across the wrist and contributes to the overall feeling of solidity. The two-tone construction gives the watch greater visual prominence than an entirely silver-tone configuration and makes it particularly suited to those who appreciate more pronounced aesthetic accents.
When using the chronograph, the physical separation of the registers makes it possible to identify the different indications quickly without compromising the readability of the main time display. In everyday use, its versatility becomes evident: the watch pairs easily with casual clothing while retaining a sufficiently polished presence for more elegant settings, preserving its sporting identity in both contexts.

The main strength of this model is the balance between chronograph functionality and an immediately recognizable aesthetic personality. The anthracite dial and two-tone configuration give it more character than many more basic quartz chronographs, while the arrangement of the indications retains genuine practical value in everyday use.
The compromises are equally clear. Hardlex is less scratch-resistant than sapphire, while the two-tone aesthetic is less neutral in terms of styling than an all-steel chronograph. Its wrist presence is also substantial, making it particularly suitable for those who appreciate visually assertive watches.
Considering its launch price, the value for money is convincing for the specifications offered. It is particularly well suited if you are looking for an accessible, functionally complete, and less anonymous Japanese chronograph than the monochromatic alternatives in the same category. The verdict is positive: a practical and well-defined proposition in which quartz convenience and sport-elegant styling achieve an effective balance.
