🔧 What it does & how to use
Each ball is a slightly tacky rubber friction opener used to unscrew and re-tighten smooth, screw-down watch case backs without scratching or marking the case — a standard bench tool for watchmakers and keen hobbyists working on screw-back cases such as those found on Rolex, Omega and similar models. Having all three colours together makes it easy to keep grip sizes to hand and swap between them for different case diameters.
- Position: press the ball firmly and squarely onto the centre of the case back.
- Loosen: turn anticlockwise while keeping steady downward pressure to break the seal.
- Remove: once loose, lift the back away by hand.
- Refit: place the case back and turn the ball clockwise to screw it back down securely.
⚠️ Please check these balls work by friction grip and are only suitable for smooth, unslotted screw-back cases — case backs with notches or slots for a wrench-type tool will need a different opener.

ABOUT US
We are a growing business that sources and imports our products as close to the actual manufacturers of the tools and parts as possible, and therefore get the best prices, no middle men.
We then pass these substantial savings onto our customers. We aim to provide very high levels of customer satisfaction with outstanding quality/price.
Postage to the UK is free.
If you are outside the UK we can combine the postage. If you could not request an invoice before paying, then buy the items and then send us message after to refund the excess postage.
We will only charge at cost, not per item. If items ARE light they can often go for the cost of 1 shipping price. You do need to message us after purchase. More valuable orders need to be sent tracked.
We generally post same day as payment if bought before 2pm.
We send our items well packed and always first or second class for the UK, and by Royal Mail Airmail for international orders.
Ebay shipping times are an estimate for international purchases and can take longer especially when not tracked.
If you buy a substantial order we will send using tracked postage at our expense if postage charged does not cover this.
Our goods are sent royal mail unless they are heavy items that then go by courier.
Our aim is to only sell good value quality goods, but should you not be 100% happy, we offer a full refund, no questions asked for up to 60 days after purchase and for any reason, just return product to us.
If an item is faulty we will pay return costs for you.
If not happy with item, please give us the chance to try to address the problem before leaving feedback. We can normally resolve any situation.
Please include your details on a note in return with either your surname or username so we can find order.
