Power Reserve
Power Reserve is a key feature in luxury watches that shows how much energy is left in the watch before it needs winding. Think of it like a fuel gauge in a car – it tells you how much longer the watch will keep running. This feature is particularly important in mechanical watches, which run on the energy stored in their mainspring rather than a battery. Watchmakers often mention this term when describing a watch's capabilities, and it can be displayed on the watch face as an indicator showing hours or days of remaining energy.

Example Interview Questions
Senior Level Questions
Q: How would you diagnose and repair a faulty power reserve indicator?
Expected Answer: A senior watchmaker should explain the systematic approach to testing the power reserve mechanism, identifying common issues like worn gears or springs, and proper calibration procedures. They should also mention documentation and quality control processes.
Q: Can you explain different types of power reserve displays and their mechanisms?
Expected Answer: Should be able to describe various display styles (linear, circular, retrograde), explain how they connect to the mainspring, and discuss the advantages and challenges of each design.
Mid Level Questions
Q: How do you ensure accurate power reserve readings?
Expected Answer: Should explain the calibration process, testing procedures, and how to verify the accuracy of the power reserve indicator against the actual running time of the watch.
Q: What affects a watch's power reserve duration?
Expected Answer: Should discuss factors like mainspring strength, movement efficiency, complications, and regular maintenance that impact how long a watch can run between windings.
Junior Level Questions
Q: What is a power reserve indicator and why is it important?
Expected Answer: Should explain that it shows remaining running time of the watch, compare it to a fuel gauge, and explain why it's useful for mechanical watch owners.
Q: How do you maintain a watch's power reserve mechanism?
Expected Answer: Should describe basic maintenance procedures, cleaning requirements, and when to seek help from more experienced watchmakers.
