Seiko Limited Edition 2018 “The Black Series”

Seiko launches three popular diver’s timepieces from their collection, but in an all black case. The three watches are namely the SRPC49K1, a three hands automatic diver with the iconic ‘turtle’ case shape, and two solar quartz watches, the SSC673P1 chronograph and the SNE493P1, a time-only diver.

The SRPC49K1 is sized at 45 mm and uses the 4R36 automatic movement.


All three watches share similar specifications in dive depth, at 200m, a stainless steel case, hardlex crystal and a similar color scheme dial design. The hour markers use Seiko’s Lumibrite coating, which curiously resembles a patina Tritium lume.

Among the three watches, the SRPC49K1 which uses an automatic 4R36 movement is easily the most desirable for many collectors. Although Seiko can be seen as spinning off multiple editions to essentially the same watch, this variant in a ‘black coating’ case could still be a fun addition for those who already have a regular steel turtle.

The SSC673P1 is sized at 43.5 mm and uses the V175 solar quartz movement with 6 months power reserve.


Seiko SNE493P1 solar diver

The SNE493P1 is sized at 43.5 mm and uses the V157 solar quartz movement with 10 months power reserve.


Unlike the more traditional automatic SRPC49K1, the solar powered timepieces uses Seiko’s solar technology that is able to convert all types of light into energy to power the watch. While the automatic 4R36 movement beats at 21,600 vph and has 41 hours power reserve, the solar powered SSC673P1 and SNE493P1 have 6 and 10 months of power reserve respectively. That said, it is not the most sensible to draw a mechanical or a quartz movement into comparison, since both function for different needs.

Seiko has announced that the watches are a limited edition but there has been no affirmative word on the numbers to be released or an official retail price. An estimated price for the Automatic Diver SRPC49K1 will be S$740, the Prospex Solar Diver SNE493P1 at S$610, and the Prospex Solar Diver Chronograph SSC673P1 at S$660.
