Seiko 5 Sports Automatic Solid Boy Grey Dial Silver Steel Mens Watch SRPE51K1
The Case:
The 40mm silver case of this Seiko 5 Sports SRPE51K1 model is made from polished stainless steel, which offers the wearer unparalleled levels of anti-corrosiveness, as well as ensuring greater shine longevity. Hardlex glass has also been used in order to provide further protection. There is also a non-screw down crown present besides the 4 o’clock marker, the crown guard has a brushed finish, which creates a subtle, yet satisfying, contrast between it and the rest of the polished case. The sleek modern motif is extended through to the silver fixed bezel, that sets this 2020 Seiko 5 Sports model apart from its predecessors that featured a uni directional bezel. The case back is transparent, which allows the wearer to view the inner mechanisms of the timepiece.
The Strap:
The silver stainless steel bracelet features a three link oyster style. The maximum bracelet setting is 23cm which can then be fastened using a fold over clasp. It also sits at a tidy lug width of 20mm which complements the 40mm case well. This bracelet is sure to catch to eye when glistening in the sun.
The Dial:
The minimalistic sunburst grey dial of the watch provides the timepiece with its cutting edge looks, as it reminiscent of something belonging to the space age. The metallic dial is complemented by the lume filled indices and hands. The hour hand comes in a cathedral style, whereas the minute hand comes in an arrow style, both have an elegant polished silver trim. The second indices are positioned within the chapter ring which is another subdued, but pleasing, touch. A day date window replaces the 3 o’clock marker, this can be displayed in either English or French. The new Seiko 5 Sport logo is present beneath the 12 o’clock marker, whilst ‘automatic’ is displayed above the 6 o’clock mark.
The Functions:
The Seiko 5 Sports range boast Seiko’s new upgraded 4R36 automatic. It is the same movement that is found in more expensive Seiko models, such as the ‘Turtle’ that belongs to the Prospex range. The movement consists of 24 jewels and it operates at 21,600 beats per hour, this ensures the watch has 40 hours of power reserve. It includes Seiko Diashock, which essentially protects the inner mechanisms from any damage the watch may sustain if it were to be dropped or knocked. It is expected to either gain or loose between +45 / -35 seconds per day.
The watch also comes with a hacking function. When the crown is pulled out to adjust the time the second hand will stop. This allows you to set the second hand for precision timing. Once the crown is pushed back in the hands will tick from that second.
Finally, this watch has a water resistance of 100 metres, making it suitable for swimming and snorkelling.
