Type 1 (SCOC)

Serial Number Range: 503xxx-696xxx

Notes: This dial is the earliest variant of the “Superlative Chronometer / Officially Certified” (SCOC) dial on the 1675 and this designation continues until today.

Type 1 vs Type 2: Between these dials, the most obvious difference is in the coronets. The crown of the Type 1 has a characteristically small base and is skinnier than the other chapter-ring coronets, looking a bit more like a child’s drawing – but charming in it’s own right. The Type 2’s is larger, wider, and has a longer but flat and symmetric base. With regards to the font changes, I look to the Type 2 with its characteristically flat and wide top of the A in “Master,” stretched top and bottom portions of the S in “Superlative,” and the skinnier O in “Officially,” to name a few.

Type 1 vs Type 3: The text and spacing between the Type 1 and Type 3 dials are also easily distinguished. First, notice the differences between the serifs in the lower bar of the L and the upper and lower bars of the E in Rolex – much larger and more angular on the Type 3. Also note the spacing of the L over “Oyster-Perpetual” – the left edge of the Type 1 L starts perfectly with the first P of ‘perpetual’ and ends over the R whereas the Type 3 L starts to the left of the P and ends over the E. Other small differences can be seen throughout the lower text.
