Seiko Prospex 'Black on Black' One Hundreth of a Second Speedtimer Solar Chronograph Mens Watch SFJ003P

The Speedtimer Prospex watch collection represents Seiko’s professional timekeeping heritage and takes inspiration from the brand’s innovative history.

This particular model SFJ003P1 is powered by a new in-house solar chronograph calibre equipped with a stopwatch which measures time to the nearest 1/100th of a second. This new release model commemorates the 40th anniversary of Seiko’s world-first analogue quartz chronograph, the 7A28. The Black subdials and black – ‘black on black’ coloured dial of this particular timepiece achieve visibility and legibility due to its separate indicators for time and chronograph functions.  Conveniently solar-powered; the watch charges from both natural and electric light.

Becoming official timekeeper for Tokyo’s 1964 Olympics was a turning point in Seiko’s history when the brand began making precisely accurate professional sports timing instruments, with no prior experience. This legacy continues today as Seiko is the World Athletics Official Timekeeper since 1985, supplying timing and measurement services to more than 180 World Athletics events in every corner of the globe.

The hammer-shaped button allows for easier operability of the stopwatch function. This model is powered by the in-house built Solar chronograph calibre 8A50 that allows measurement to the nearest one-hundredth of a second.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.

Featuring the Seiko Solar 8A50 movement, the SFJ003P has an approximate accuracy tolerance of +/- 15 seconds per month and a 6 month Power reserve once fully charged. This model is finished in full Stainless Steel with a pull-out crown. The hands and the markers have lumibrite to make them visible at night (once fully charged). The case size is 42mm and thickness 12.9mm with a lug to lug size of 48.3mm and a lug width of 20mm and the entire watch weighs approximately 150gm. 

The additional features of the SFJ003P Speedtimer are a Screw case back, Tachymeter function, 24 hour hand, a chronograph up to 60 mins in 1/5 second increments, a date display, with a Chronograph up to 60 minutes in 1/100 second increments and an overcharge prevention function.

What we love: The finish and the overlook look is simply classic. Destined to be a Seiko cult classic collectors model with an amazing history and lineage.
