Most original dials in the c.852x series have single hour "slashes" in the Calatrava style with luminous dots. In fact, these hour markers are the classic style for both the 852x and 853x series. The most common dial colors were silver or white (with a milky, silverish tint). Black dials were also used and are not uncommon. Most Ingenieurs with the "classic" style have a double slash at 12, which sometimes had a space between them (see catalog picture below) and sometimes not. There were also 852 Ingenieurs with Arabic numerals and those with "pie pan" dials (that is, with the center raised above the outer chapter of the dial).Most known original hands were dauphine-style (triangular) filled with tritium. It is possible that the earliest models had radium treated dials as explained in the . Some early models may also have had baton hands as evidenced by recent IWC catalogs (right). Some models were equipped with indices (i.e., hour markers) in white or yellow gold. According to the catalogues, all models except the non-date versions in stainless steel (ref. 666 A) or in mixte (ref. 766 A) received gold indices.

Another distinguishing characteristic of the 852x and 853x's Ingenieurs is their watch cases carried their 7-digit case number engraved between the 6 o'clock (bottom) lugs. The c.8541 series did not have this feature and instead had their case numbers inscribed either on the inside or outside of the 12-sided screwbacks.

Most cases were produced in stainless steel, although 18kt and mixed versions (14kt with stainless steel back) were also available. The 18kt versions were primarily yellow-gold, although pink and white gold examples were produced.All regular production dials of the Ingenieur carried the logotype of "International Watch Co" in script with Schaffhausen in a slanted block type underneath. Some examples of the 853x models also include either an applied or printed "IWC" logo above this script. If these dials are not the result of a later replacement, they might indicate a transition to the 2nd Ingenieur generation.. Depending on who created the dial, there are other very subtle differences among Ingenieur dials that are visible when comparing pieces side-by-side. For example the lettering and spacing of SWISS (and later T-SWISS-T) at the bottom of the dial. These more subtle variations are presumably the consequence of the fact that IWC's dials and hands were produced at different times by different suppliers in relatively small lots.
