Family owned & run since 2006

The people behind the counter

Cassims & Co. opened in 2006 and is still owned and run by the family whose name is above the door.

Twenty years in the trade has made us an authorised dealer for more than twenty watch brands — and given us what most jewellers don’t have: our own design and manufacturing studio and a dedicated watch service centre, on site.

Everything runs through one team. The people who advise you in store, the people who make and look after the pieces, and the family who runs the business, all held to the same standard. We would rather take the time to understand what you are looking for than sell you the nearest thing to it.

That standard does not move: the finest quality we can source or make, and service worth coming back for. Twenty years in, we are still pushing — new brands, new techniques, a higher bar than the year before.

Thousands of clients come back to us — for the upgrade, the anniversary, the proposal, and often for the generation after that.

Very happy with the service and product. I ordered online and it arrived way sooner than expected and the service was great. My finance loves the ring and it fits him perfectly! Has a great weight to it so it’s really nice quality. Would highly recommend :)

Hi, some months ago I lost my Tag Heuer AQUARACER watch and have been searching for a replacement worldwide. As a last attempt I tried Cassims and found nearly the exact watch but with a very slight colour variation. i did the purchase on line, it was delivered in the stipulated time and i am thrilled with it. It was also about 60% less than a new one! The design was discontinued so new wasn't an option.... Thanks to all who assisted. Else Hall/George W Cape

I live in the Kalahari in the Northern Cape. I looked at Cassim and Co online when I was searching for a nice watch. I saw something I like, advertised with a discount voucher. I enquired via telephone with one of the staff. I dealt with a LOVELY and MOST HELPFUL lady by the name of Tessa. What a WONDERFUL experience. She sent me all the photos from all my requested angles, and told me everything I needed to know about the relevant watch. With the necessary assurances. I purchased the watch, on her recommendation and information, and it was couriered to me overnight at no charge. I am THRILLED with my purchase. It is everything Tessa assured me it would be. I woukd like to commend Tessa on her EXCELLENT and extra-mile service. I will, without a doubt, call on her again for anything I fancy. I HIGHLY recommend Cassim and Co for their staff excellence and knowledge. Heather

We were so pleased with the quality of service we received from Cassims & Co. A huge thanks, specifically to Sherley, who was incredibly responsive and proactive. From quoting and answering queries to following up and meeting delivery expectations, all boxes were checked. Outstanding work by the Cassims & Co team. Highly recommend your watch and engraving services!
