The Queen has a specialist team of clock masters that spend 40 hours tweaking over 1,000 clocks in her residences for daylight-saving time
- There is a team of people hired by the royal family to turn back the clocks for daylight savings.
- They're called horological conservators and are responsible for over 1,000 timepieces.
Queen Elizabeth II needs a whole team of clock experts to spend a weekend manually changing each timepiece across her royal residences so they are ready for the one-hour time change under daylight-saving time.
The jobs of royal clock masters, known professionally as horological conservators, were spotlighted in a video posted by the official royal family Twitter account on Saturday, before daylight-saving time in the UK kicked in on Sunday morning.
Captioning the tweet, the account revealed how there are over 1,000 clocks across royal residences, and each is looked after by a specialist who comes in twice a year to tweak them before the time change. Lead horologist at Windsor Castle, Fjodor van den Broek, who says he's also known as "clockmaker of the castle," is featured in the video - he drops by the castle once a week to check on the clocks.
"I get to know every clock very well," van den Broek said in the video. "We have 400 clocks on the estate, of which 250 are inside the castle and the rest are distributed around the estate."
Clocks in the residences need service every few years on top of the biannual clock change, he added.
"When we set the clocks backwards in winter it's a bit of a different process for every clock," he said. "In summer it's much easier because every clock just goes forward one hour and for each time it takes me about a weekend to set all the clocks to the right time."
Clocks in the Queen's residences are part of the Royal Collection Trust (RCT). Per the RCT website, staff spend 40 hours tweaking them individually before daylight-saving time kicks in. Buckingham Palace has the most at 600, while Windsor Castle has 450, and the Palace at Holyroodhouse has 50.
Buckingham Palace and Fjodor van den Broek did not immediately respond to Insider's request for comment.
