■ What is a speed timer?

The Prospex Speedtimer is a series created as a homage to the 5 Sports Speedtimer, which Seiko released in 1969 as the world's thinnest automatic chronograph. It is a true lineage of sports watches that incorporates the DNA of authentic racing watches of the time into modern solar chronographs.

SBDL129 is a variation in the series that uses an opal green dial. In a sports watch market dominated by black and blue, I would like to honestly praise the courage to choose this color. However, it is not too flashy and has a perfect balance with the calmness of the sand grain pattern.

■ Opal green option

The most distinctive feature of this model is the dial color. Opal green is a deep color that changes its expression depending on the viewing angle and how the light hits it. It gives off a subtle presence not only in casual denim styles, but also when matched with a jacket.

Compared to the same series SBDL127 (black), the coloring brings out more individuality. However, the completeness as a sports watch is not compromised at all. This model has the fun of choosing by color.

■ Fullness of specifications expressed in terms of functions

The solar chronograph equipped with caliber V192 is equipped with a stopwatch function that measures 1/5 second and 60 minutes, as well as a power reserve display, 24-hour hand, and tachymeter. The operating period when fully charged is approximately 6 months, and the accuracy is stable with an average monthly difference of ±15 seconds.

A tachymeter is a function that allows you to calculate the average speed of a measurement object over a specific distance. It is used in conjunction with the scale engraved on the bezel and a chronograph. It is a symbolic feature of racing watches, and is also the origin of the name Speed ​​Timer.

Lumibrite is applied to the hands and indexes, making them clearly visible even in the dark. The 10 ATM water resistance and screw back structure ensure that it can withstand tough usage environments.

■ Authentic specifications seen in the case and glass

Case size is approximately 46 x 39 x 13.5mm. The 46mm lug width has a strong presence as a sports watch, while the case diameter is 39mm, which is a well-balanced sizing. The arm circumference can be up to 20.5cm, so it can be worn by a wide range of people.

The glass is curved sapphire with anti-reflective coating on the inside. Sapphire glass is several times harder than mineral glass, making it much more resistant to scratches. The inner coating suppresses reflections and further increases the visibility of the dial - a finish unique to authentic sports watches.

The case material is stainless steel, and the band is also a stainless steel C-ring type. The finish, which combines hairline and mirror polish, creates a sporty and fearless impression.

■ Buyer's comment

To be honest, at first I thought "Will it sell?" about the Opal Green Speed Timer. However, the moment I put the actual product on my arm, I felt strangely satisfied. The sand-grained dial moderately suppresses the emphasis on the green color, and there is no clunky impression at all. The combination of hairline and polish is also carefully done, and I feel that the finish is better than the price range of 99,000 yen. It has three pillars: solar power, 10 ATM water resistance, and sapphire glass, making it the perfect companion for everyday use.
