The Watch & Clock Center, which specializes in special timepieces and repair, is a good local source for consultation and appraisal services. Its store also carries a variety of fine jewelry items. Many orderly glass display cases fill this roomy store, which occupies a vintage corner storefront at Park Avenue. The sales staff has a lot of experience, which lends to very credible advice on purchases and repair issues. Cost-saving remedies for small service fees are the norm here.
