The Spring Drive Caliber 9RB2 boasts an accuracy rating of ±20 seconds per year, positioning it as the most precise mainspring-powered movement globally.
Ever-Brilliant Steel offers a brighter sheen and superior corrosion resistance compared to standard stainless steel.
The redesigned bracelet clasp allows for quick, toolless sizing via an integrated micro-adjustment system.
The 37mm SLGB015 'Lake Suwa' model provides a highly requested downsized footprint for the flagship collection.
The 40mm models maintain the collection's traditional, highly sculpted case blueprint.
Dial variations include 'White Birch' (silver-white texture), 'Atera Valley' (vivid green), 'Lake Suwa' (deep blue ripples), 'Lake Suwa at Night' (smoky dark brown-black gradient), and 'Green Birch' (deep forest green vertical texture).
The 'Genbi Valley' dial features a light-blue crystalline pattern inspired by river waters and rock formations.
The core aesthetic of the E9 line is preserved, featuring low centers of gravity, broad multi-faceted lugs, and a double-wide index at 12 o'clock.
