Seiko King Sumo Prospex Men's Watch -  SPB323J1 has a graduated grey dial.


The king sumo are far more premium than the cheaper Sumo variants with sapphire Crystal and ceramic bezel.  They also have a nicer strap which is not pressed steel like the cheaper versions.  It was purchased on the 01st November 23 so has the balance of the Seiko 2 year UK warranty.  The warranty card, booklet and box are all included. 


Please note this is a UK sale only due to value.


The watch has only been worn a couple of times and looks like new.  It may have some tiny hairline marks but I cannot see any.


Retail for these is £1150.00


I am thinning out watch collection post retirement and this was an impulse buy but just not getting any use.


It has the improved 6r35 movement with a 70 hour power reserve.

ately named ‘Sumo’ by Seiko fans because of its size and shape and the 12 o’clock marker – it’s a substantially strong looking timepiece.


This latest design has been upgraded with new modern features, including a ceramic bezel and super hard coating on the case and bracelet for durability. A new 3 row bracelet has been specifically made for this model, while the clasp has also been upgraded. The dial features a fine pressed pattern dial with gradations of grey.
