Lip Thermometer watch ref 42670 from the 1970s

The French brand LIP made some seriously cool, and quirky designs in the 70’s, take this obscure Lip Thermometer watch, which actually measures temperatures using the central dial and uses a upgraded Durowe movement. This watch is with crosshair dial and neon colouring. A great example of experimentation in the Swiss watch industry.
