SEIKOProspex 3rd Gen"Sumo" Diver's 200m Automatic Green Dial Sapphire Glass Watch SPB103J1

Love this watch . however yesterday it quit working. i purchased it in march who do i need to contact since it is still under warranty?

Hoe many jewels?

how long is the warranty? I'm concerned that it is not specified anywhere in the item description.

What is the lug to lug measure? Does it wear big? My wrist is on.the smaller side. Thanks.
