Hello Forum I bought Panerai Luminor 7 hr. ago. 3.5 years ago the watch stopped working reliably, would not keep charge. In Panerai they told me it requires 3-4 years maintenance, so I spent $500 for maintenance. Now it happened again. For comparison, Rolex submarine is 6 yr. older and required maintenance at the same time, which is 10 yr. after purchase. Is it normal for prime brand like Panerai to require so high maintenance? I find hard to believe. While any mechanical watch require maintenance, it's reliability, design should require a lot less maintenance. Or what else make the watch so good? It's price or frequent advertizing?
