Questions and answers

Is the King Samurai worth it over the standard Samurai?
The King version adds sapphire crystal and a slightly larger case. If you want scratch resistance without a mod, it is the simpler buy. If price matters more, the standard Samurai with hardlex is cheaper.
How accurate is the 4R35 movement?
Seiko rates it at -35 to +45 seconds a day. Most examples run closer than that, but expect to reset the time every week or two.
Can I put it on a bracelet?
Yes. It has 20mm lugs, so any 20mm strap or bracelet fits, including Seiko's Samurai bracelets. The watch ships on silicone only.
Is it good for actual diving?
It is rated to 200m with a unidirectional bezel and screw-down crown, so it meets the basics for recreational diving. Many owners use it as a daily watch instead.
What is in the box?
The watch on a silicone strap, a Seiko presentation box and paperwork. No extra strap or tool is included.
When is it cheapest?
Seiko dive watches tend to dip during seasonal sales and when a new colorway launches. Check the price history here before buying.
