Summary

• The Clock Tower is a building unlocked at Builder Hall Level 4.
• It appears to be a Tower with a clock on top in which a hand turns clockwise.
• The Clock Tower's hand turns very fast when boosting.
• When activated, the Clock Tower will make timers in the Builder Base speed ten times as fast as normal for a short duration. This duration can be increased by upgrading the Clock Tower.
• It will speed up resource collectors, construction, upgrades and research timers.
• The Clock Tower will not reduce the cool-down time of loot from Versus Battles.
• The Clock Tower will occasionally make a free boost available. Once a free boost has been completely expended, there will be a 22 hour cooldown before the next free boost is available.
• If the Clock Tower is not active, it can also be activated using Gems. A Clock Tower Potion can also be used to boost the Clock Tower for 30 minutes at any time (this duration is independent of Clock Tower level, and the potion works regardless of whether or not the Clock Tower is active).
• Upgrading the Clock Tower will disable its ability to boost during the upgrade. If a Clock Tower upgrade is started while a boost is active, the boost will end prematurely with no compensation.

Strategy and Tips

• Use the Clock Tower's boost when upgrading or researching something in the Builder Base. However, the Clock Tower will not boost the Master Builder when he is working in your Home Village.
• Even if the Star Laboratory and builders are inactive, it can still be useful to boost, as it still speeds up resource production slightly (gaining a few hours' worth of Builder Gold and Elixir).
• The Clock Tower is best placed outside the base as a distraction as it serves little, if any purpose on defense. Its 4x4 space makes it difficult to fit within the Walls. Additionally, due to its larger size, it may be easier to pick off than other buildings if defenses aren't placed properly.
• The Clock Tower can be used to hide an opening in the Walls which can cause unexpected behavior in certain troops (such as Boxer Giants), and can also be used to funnel troops into traps. However, experienced players can see through this trick (for instance, by counting the wall segments) and plan their attack accordingly.

Upgrade Differences

Each time the Clock Tower is upgraded (depending on what level) you can see Roman numerals (I-IX) on the left side that corresponds to the level of the Clock Tower.
The Clock Tower goes through significant visual changes at levels 1, 3, 5, 7, and 9.

• At level 1, the Clock Tower is rebuilt from its broken state but parts are still in disrepair.
• At level 2, the roof planks are fixed and reinforced.
• At level 3, the front undergoes a major repair. A large ladder is placed on the front. The upright barrel at the side switches place with the sideways barrel. A trapdoor replaces the repairs on the roof. There is also additional stairs below the doorway. The Clock Tower seems to be slightly taller.
• At level 4, the trapdoor hinges become metal and a metal frame under the trapdoor appears.
• At level 5, the ladder is replaced by a cross in the front. You can also now see the gears inside through the "window" on the side of the tower.
• At level 6, the holes in the trap door on top turns into a whole piece of metal.
• At level 7, the front-bottom part gains two openings with one rotating gear each. The two front pillars gain some extra reinforcements and the side gains more steps.
• At level 8, the hatch at the top of the tower is raised slightly, leaving a small opening where a bell can be seen.
• At level 9, the gears are now golden while the hatch at the top of the tower is raised higher. The staircase receives railings on both sides.

Trivia

• The Clock Tower sits with obstacles at the left side of the map when broken.
• On 6/26/2017, the Clock Tower's boost duration was reduced by 50%, its boost speed was reduced to 8x (from 10x), and its cool-down time was reduced to 7 hours (from 8 hours).
• On 3/30/2020, the Clock Tower's boost duration was greatly increased, and its boost speed was increased to 10x (from 8x). Its cool-down was increased to 22 hours (from 7 hours).
• Above the door of the Clock Tower, you can see Roman numerals which correspond to the building's level. This is also on the Star Laboratory.
• The Clock Tower's hand makes a full rotation every 30 seconds. This is double the speed of the second hand on a regular clock.
• While a boost is active, many animations also appear to speed up as well. The Master Builder, Villagers as well as Troops stationed in Guard Posts and Army Camps move faster. The latter is purely aesthetic; troops will not move or attack faster during a Versus Battle while under a boost.
• The Clock Tower was added on 22/5/2017.
• Interestingly, when fixing the three broken buildings in the Builder Base, the Gem Mine and Battle Machine fixes are called a "rebuild", while the Clock Tower is called a "repair". In fact, the Clock Tower is the most broken out of the three, thus the one that needs a rebuild the most.
