Complementing the chronograph is the SLGW007 “Moonlit Birch,” a manual-winding hi-beat dress watch that evokes the bark of white birch trees bathed in moonlight. Its textured navy PVD dial mirrors the irregular forest patterns of Iwate Prefecture’s Hiraniwa Plateau. Arriving in a slender 38.6 mm stainless steel case, the timepiece measures 9.95mm in thickness. Inside, the Caliber 9SA4 vibrates at 36,000 vph to maintain stability and accuracy, delivering 80 hours of continuous running power. Echoing the dial’s grained pattern, a navy-toned calf-leather strap completes this understated timepiece with quiet elegance.

Available from October, the SLGW006 “Sunrise Tentagraph” boasts a price tag of $22,600 USD/£19,650 GBP and will be sold through Grand Seiko Salons. As for the SLGW007 “Moonlit Birch,” it will retail for $10,000 USD/£8,600 GBP, also releasing in October. Visit Grand Seiko’s official website for full details.
