How much does H.L. Gross & Bro. Jewelers charge?
They do not publish prices and we have not yet rung them to ask, so we leave it blank rather than estimate. Call (516) 747-6666 and ask for a written quote with your reference number on it.
Does H.L. Gross & Bro. Jewelers have a watchmaker on site?
Their own website states there is a watchmaker on the premises, so work is not sent out.
Is H.L. Gross & Bro. Jewelers an authorised dealer?
Yes, for 1 brand. We only record authorised status when the brand's own retailer locator confirms it, and that source is linked on this page.
Has this listing been verified?
Partly, and the distinction matters. Address, phone, hours, brands and services were compiled from H.L. Gross & Bro. Jewelers's own published pages on 10 September 2026, and every source is linked here. Nobody has telephoned them to confirm prices, turnaround or warranty, which is why those fields are empty rather than estimated.
