Prospex Seiko Watchmaking 110th Anniversary Limited Edition. To mark 110 years of watchmaking excellence, Seiko is highlighting its continuous dedication to evolving technology, as well as diversity, equality and the sustainable manufacturing necessary to meet environmental challenges. Available only in a controlled-production run of 3,500, this exceptional Limited Edition celebrates both the 110th anniversary of Seiko watchmaking and the 40th anniversary of Seiko's – and the world’s – first analog quartz chronograph, which offered a 1/100-second stopwatch. Featuring the new solar chronograph 8A50 movement, powered by any light source, with no battery change required and a 6-month power reserve when fully charged, this remarkable timepiece provides chronograph measurement of up to 60 minutes of elapsed time in 1/100-second increments with a split time function. The concave tops of the hammer-shaped pushers allow easy utilization of the stopwatch feature. For enhanced legibility, the uniquely designed dial includes a white base with four inset black subdials, separating the time dial from the chronograph indicators, LumiBrite hands and markers, and, in tribute to the 1913 Laurel, Seiko’s first wristwatch, red hands on the top three subdials. With a curved anti-reflective sapphire crystal, this durable stainless steel timepiece includes a screwdown caseback and tri-fold push button release clasp, and comes with an additional dark brown sustainable leather strap certified by the Leather Working Group (LWG). Packaged in a Limited Edition collectors’ box. 10 bar, 100M Water Resistant
