we can't see your return. 179 is limited by % of business use and also by business income before the 179 deduction. review form 4562. no deduction is allowed for federal purposes if you are deducting these items as an employee business expense.
as to the watch, if audited you will have to justify (provide some evidence) that it is used primarily for business
