“I took my 25 year old Breitling Aerospace in for a check up and new battery. Stu and the team did a superb job. I was lucky enough to have a look at their workshop which resembles a laboratory. All sorts of tools and gadgets available to service the watches, precise and impeccably clean. The watch came back in very good time and I really can’t fault the service. If you need your precious timepiece taken care of then these are definitely the people to trust it with.”
