Reference 7750
There are three known variations of Rehaut found in the 7750 model range. These can be found across all 7750 case marks and dial variations.
NOTE
An interesting comparison is that despite being different measurements, the 1Mile and 1km have the same marks throughout their rehaut. This lack of detail might explain that in the next reference of Orfina Porsche Design watches, the manufacturer just put "Tachymetre" solely on the rehaut without either "unit" designation.
1Mile
The 1Mile rehaut features tachymetric markings calibrated for mile-based measurements, commonly used in markets following imperial measurement systems.
1km
The 1KM rehaut features tachymetric markings calibrated for kilometer-based measurements, designed for markets using the metric system.
Advertisement Rehaut
The Advertisement version had neither 1Mile nor 1km marks, but all tachymetric scale markings. Likely unreleased in this way and possibly done to serve multiple markets with a single advertisement.
