The Seiko Prospex SPB240J1 is a contemporary reinterpretation of the iconic 1968 diver’s watch. This model features a unique brown dial and rose-gold tone accents on the unidirectional bezel that adds a distinctive vintage-inspired aesthetic to the classic tool watch design.
At its heart is the Seiko Caliber 6R35 automatic movement, offering approximately 70 hours of power reserve, manual winding capability, and reliable performance with a precision range of +25 to -15 seconds per day.
The 42.0mm stainless steel case combines polished and brushed surfaces with a rose-gold coloured bezel and is protected by a sapphire crystal with anti-reflective coating. With 200m / 20 bar water resistance, screw-down crown, and unidirectional rotating bezel, the SPB240J1 is ready for adventure both in and out of the water.
LumiBrite on hands and markers ensures excellent low-light legibility, while the stainless steel bracelet with secure clasp provides durability and comfort. This diver bridges modern performance with vintage style cues.
