The texture of the stainless steel for this model is enhanced not only with the recrystallisation and deep-layer hardening processes, but also by an additional TiC coating. The screw-lock case back also has a DLC coating applied to it and is engraved with the 40th anniversary logo. A star is engraved on the Mode button on the lower left side of the case, and the phrase “SINCE 1983” appears on the dial.
