Tissot RockWatch R150 30mm Swiss Alpine Granite Quartz Vintage 1985 Watch

Tissot RockWatch R150, 30mm Swiss quartz, Alpine granite case.  Launched in late 1985, the RockWatch was the first wristwatch with a case and dial milled from a single piece of natural stone. Because the granite is natural, no two are patterned alike, so this one is genuinely unrepeatable.  The bright yellow hour hand and red minute hand were taken from the colour-coded markers on Swiss hiking trails. Tissot built the whole thing to give people a reason to buy Swiss during the quartz crisis, and it worked.  Model: RockWatch R150, the mid-size unisex version Case: Genuine Swiss Alpine granite, 30mm Movement: Swiss ETA quartz, caliber 976.001 Introduced: Late 1985  Running and working condition. Not recently serviced; sold as-is for accuracy.  From Caseback Chron.
