On 10/26/2024 6pm, I purchased a Master Collection moon phase watch for $4,100 at Longines retail store in Aventura Mall, Miami, Florida. It instantly lost 3 minutes per day. By Tuesday it lost 9 minutes. On Wednesday morning it display 8.09 am (ET) and appeared to have stopped. This was 4 days after the purchase! I went back to the store, and asked for a return because The watch was clearly broken before I even purchased it. I really expected they would take it back as any upstanding company would do. The store manager Miriam refused and claimed that it can be repaired or "maybe" replaced. I pointed out that it would be the right thing to take it back as the watch was malfunctioning even prior to the purchase. I said that lost trust in the brand and quality of the watch. The company should demonstrate that it stands behind its brand as any 'luxury' brand would do. The store manager referred to "policy", hiding behind it. Basically, greed was more important than customer satisfaction. It is obvious that the company Longines is totally fine with selling malfunctioning watches and collecting thousands of dollars without showing any responsibility. I accepted the offer to replace the watch under protest yesterday. I fear that the watch will stop working as the other did before after a few days. Other posts on various websites show similar failures, this tells me mine is not a one-off as claimed by the store manager. Again, DO NO BUY Longines!!!!!! Save the money and headache. I lost trust, and I feel cheated. Do not fall into the same trap!
