The Corum Golden Bridge Round B113/03010 showcases Corum’s iconic vertical baguette movement inside a refined 43 mm 18K rose gold case. A diamond-set bezel, transparent architecture and brown alligator leather strap create a distinctive expression of haute horlogerie.
At its centre is the CO 113 hand-wound calibre, whose bridges, plate and decorative elements are crafted in 18K gold. The linear movement operates at 4 Hz (28,800 vibrations per hour) and provides a 40-hour power reserve. Double anti-reflective sapphire crystal and a sapphire caseback reveal the movement from both sides.

Not your typical pretentious jewellery store or AD for watches, I walk in often chat with the sales people, look at watcheswith zero pressure or snobbery. They are open and inviting, all which encouraged me now to purchase from them as well. Can't go wrong.

We went to Golden Tree Jewellers yesterday to pick out a watch for my wife. Simon was very helpful, allowed us to try on many options and never pressured us on any sale. Simon is very knowledgeable and we appreciated his guidance. Thanks again!

Customer service received was excellent. They took the time to answer all of my questions and show me a fair amount of watches before I made my decision. Opted to buy two watches after a fair negotiation and left feeling very happy with my decision to shop at Golden Tree.

My favourite luxury watch retail store in the Lower Mainland. Bob, Aavis and their staff are very knowledgeable, patient and caring for their customers. I visit them multiple times a month when I am in the mall and they engage me regardless of me buying a watch or not. I've bought two watches from them and look forward to buying more. Highly recommend you visit them if you love watches or are curious about what to buy next for yourself or your loved ones.
