Incoming 62MAS Reissue SBDX041 JDM

[ijpx]

300pcs limited edition Seiko & Beams collaboration. Features a matte black dial, 8L35, tropical straps and Seiko’s new 904L Ever brilliant steel.

This is the 4th 62mas reissue Seiko has done up till 2020 and it’s my favorite one.

Fantastic piece, congratulations. Do you have and paperwork or references for the use of 904L stainless steel? I'm not disputing it, but its the first Seiko piece I've heard of using 904L.

”To be known as Seiko’s “Ever-Brilliant Steel,” thanks to the brilliant white hue that gives this trilogy of watches its unique look, this grade of steel is more corrosion resistant than that which is used in most high-end watches today.*

* This stainless steel has a PREN (Pitting Resistance Equivalent Number) value 1.7 times higher than that of the grade of steel used in most high-end watches. PREN is a widely accepted standard used to measure corrosion resistance. “

While I am no metallurgist, a bit of quick search on the web I found that 316L steel is most commonly used in “high-end” watches, has a PREN value at around 25. 904L is in the mid 30s, while Seiko’s steel is 25x1.7 which is >40. This leads me to think Seiko uses a super duplex steel (PREN >40) that has higher Chromium and Nickel % than 316L & 904L, thus the better corrosion resistance and white hue claim by Seiko.

Whatever it is, this watch is costing close to GS price and if you compare it to SLA037J1 it’s a very good value buy, with the same side-polished case and tropical straps, difference being non hi-beat and classic black color, so I’m just happy it comes with higher specs for my money’s worth.

Thanks for the information.

Oh dear, I can only hope that this is not true. I have a nickel allergy and unfortunately react to 904L steel. That's why I had sold almost all of my Rolex because with the usual 316L steel I have no problems at all.

I just hope that Grand Seiko doesn't switch to 904 for purely marketing reasons and differentiation. Then I will lose the next watch brand.
