For anyone needing to buy or sell watches and/or jewellery I had excellent service from Sas at Alpha Buying Co who has a wealth of knowledge about gold, silver, diamonds, watches and all jewellery... Easy to find and super convenient location near the QVB; I just popped in on my lunch break. I'll be going back and highly recommend that others do too!

I can highly recommend Alpha for buying / selling jewelry, watches etc. Having dealt with Sas on many occasions, he has substantial experience, with an encyclopedic knowledge of a wide range of items. Also seems to have unique and hard to find pieces on offer along with fair buy pricing. I've been highly satisfied with all of our transactions. Conveniently located near the QVB.
