The Seiko Sumo has had no changes since 2007 until now. Nicknamed - possibly because of it's chubby case and shape. It's a fan favourite due to it's high-end looks and affordable price point.
This new Sumo watch brings in the 6R35 automatic movement instead of it's usual 6R15. The 6R35 is notable for an improved power reserve of 70 hours.
In regards to the appearance, the steel case still retains it's sharp angles and still has it's screw down crown positioned at 4 o'clock. The new Sumo still carries the same dimensions of a 45mm width and a 13.47mm depth.
A big noticeable change this re-visioned Sumo watch has acquired is it's weight loss by the change in font on the bezel. This new font is much thinner than what we're used to. Previously, the Sumo was made with mineral 'hardlex' glass and this gorgeous update fits a sapphire crystal.
Seiko Sumo in it's new form is hugely desired and has been hugely popular since it was displayed at Baselworld 2019.
