Taking double-branding to new heights. A unique Rolex-Patek Philippe ‘Master’ wall clock. Commissioned by Rolex for its workshops in Switzerland circa 1968. Patek also made smaller auxiliary clocks for the watchmakers’ benches linked to the master so they could adjust the movements using the most advanced tech available - a 100 kHz quartz timebase with an accuracy of 1/10th second per day. Part of a collection of 40 Patek Philippe electronic clocks currently with @collectabilityllc and @analogshift in NYC. #patekphilippe #rolex #electronicclock #collectibility #collectability #analogshift #dubaiwatchweek #horologyforum #telegraphtime #watchpro #bhi #horologicaljournal 🎥: @mingliuwrites
