These Elapsed Time Indicators (ETI) are designed for use wherever elapsed time must be accurately measured and accumulated. The elapsed time is an indication of down time, equipment maintenance period or performance evaluation. The larger avionics boxes will be fitted with an electro-mechanical device that can be read externally by Maintenance Engineers but a small module or card can sometimes host a miniature chemical ETI.

C1058: This is an electro-mechanical ETI marked on the front "Hours" and on one side in white ink: "ETI.1". It is not known which unit this was used on.
