For sale or trade is my Seiko MM 300 reference SLA021. This watch was purchased Jan 2021 from Gnomon in the US. Comes with box, inner pillow, tags, warranty paper, manual, steel and silicone strap.
Measures ~44mm diameter by 15mm in height. I find it wears smaller than the stated dimensions due to the lug to lug span. Powered by the GS caliber 8L35, ceramic bezel with lume and a sapphire crystal. A great sturdy tool watch and diver!
This watch has seen little use and is in excellent condition. Currently is being worn on the silicone strap so the steel strap is in great shape, with some minor hairlines. Case is quite clean with maybe a couple hairlines as well but that's it.
