The inner tachymetre (or also found as tachymeter) scale is found in black, grey and white. The most common version of the scale starts at 500 or 300 km/h finishing at 60.
The most common dial version known is black with white sub dials. The Enicar logo is applied and the logo and fonts are similar in style to the Mark III. On some dials the words Sherpa Graph can appear slightly bolder or even slightly fuzzier than the Mark III dials which we believe is down to less stringent quality control methods by Enicar. Other variants also exist with the most common being the white dial version with either grey or silver sub-dials, a black dial version with grey sub-dials and a blue dial version with white sub-dials.
The hands are the major change from the Mark III. The minute and hour hands are in the batton style with white paint around the lume (black paint at the white dial variation).
The seconds hand is typically of the triangle variety also seen on the Mark III and Mark IV Aqua Graphs. These are typically orange but also appear in red. Some examples have been seen with a lollipop hand and red dot.
The sub-dial hands are thick and painted black. The minute counter hand will be orange or red to match the chrono seconds hands and are sometimes seen in plain black.
Although the Sherpa Graph was more like a racing watch h you will find the waffle compressor crown with Enicar saturn on it.

The back shows the Sherpa 300 logo with the seapearl in the middle.
