The owner's watch has stopped. It is sitting on the dresser showing Tuesday when it is Friday, and it would take you four seconds to spin the crown and put it right. Every instinct you have as a good stew says fix it. Do not touch it. That four seconds is the single most common way a crew member destroys a movement and ends up paying for a fault that may already have been there.
Why winding and setting are forbidden
- Date mechanisms have a danger zone. On many watches, changing the date while the hands sit roughly between 9pm and 3am can strip or jam the date change wheels. The damage is invisible until service.
- Overwinding and cross-threading. A hand-wound movement can be wound past its stop by someone who does not know the feel. A screw-down crown that is pushed and turned at the wrong angle strips the threads and destroys the water seal.
- Chronograph pushers are not toys. Pressing them underwater or against resistance can bend the levers.
- You cannot prove prior condition. If the watch was already faulty, the moment you touched it, it became yours.
The rule is absolute and it is easy to remember: you do not wind, set, adjust, wear, test or open a guest's watch. Not to be helpful. Not because the guest "wouldn't mind". Not even if a colleague tells you it is fine.
Watch winders
Some yachts carry a winder — a box that rotates to keep automatics running. Use it only when there is a standing instruction from the guest or the chief stew for that specific watch. Otherwise leave watches stopped. A stopped watch costs nothing; a winder set to the wrong direction or turns-per-day is at best pointless and at worst a small ongoing act of wear. If you are asked to place a watch in a winder, log it: which watch, which slot, on whose instruction.
Magnetism
Modern life is full of magnets and mechanical watches hate them. A magnetised balance spring makes a watch run wildly fast, and the guest will notice.
| Source | Where you meet it | Rule |
|---|---|---|
| Speaker magnets | Cabin audio, headphones | Never rest a watch on or beside a speaker |
| Magnetic clasps, phone cases, tablet covers | Everywhere | Keep watches off and away from them |
| Induction hobs, tools, motors | Galley, engine spaces | Watches never travel through these areas |
Magnetism is not damage in the mechanical sense — it is corrected at service — but the guest experiences it as a fault, and the fault will be attributed to the last person who handled the watch.
If a guest asks you to set it
Say, politely, that you are not permitted to adjust guest timepieces and that you will pass the request to the chief stew. That is not unhelpful. That is the answer that keeps you employed.
Onboard Notes
- Never wind, set, adjust, wear, open or test a guest's watch. No exceptions.
- Date changes near midnight can wreck the mechanism. That is why the rule exists.
- Winders only on standing instruction, and log the placement.
- Magnets make watches run fast, and you will get the blame.
