Sanwu brand is a well-known trademark in the watch industry. You are different from it, but you are similar enough to cause misunderstanding among consumers and constitute trademark infringement. You can't use it. Although you have registered the copyright, your copyright is similar to others', which constitutes imitation and can be revoked. Although copyright and trademark are different fields, your use of clocks and watches violates the principle of good faith and must not be used. Change the brand. If it can be used, others have already used it. You know, we are old imitators.
