SEIKO Prospex Divers NEW SUMO REFS.

Here’s a very quick look at a couple of new Prospex Divers for 2019; refs. SPB101J1 which is in black and SPB103J1 which is in green.

These are updated Sumo Divers, if you will that Seiko will be officially releasing sometime soon. The updates include new movements and new crystals.



The movement will be 6R35 caliber with 24 jewels, a beat-rate of 21,600bph and 70hrs of power-reserve.

The 6R35 will be housed in the same 45mmm x 13.5 x 52.5mm lug-lug Stainless steel case which will be fitted with a new Sapphire crystal. Not sure if the cases get Dia Sheild or not?



Water-resistance is 200m. Expected MSRP will be circa 960USD.

BTW if you were ever wondering where the Sumo nickname came from – the 12 o’clock index is said to resemble a Sumo’s mawashi.
