Rolex submariner

[Adam100]

Hi and happy new year.

Im new at this forum and I have a question about a brand new Rolex submariner 16610.

I bought it 2 weeks ago brand new at a AD. I have worn it everyday and the day I bought it I rewind it maunally 20 times.
It has worked perfectly but yesterday it stopped when I took it of for 1 hour.

I rewind it manually again and now it works perfektly again(it has only gone 1 day since it stopped).

1. I have only rewind it manually once,mayby I have to rewind it twice a month?

2. I dont wear it when I do sport mayby thats the reason?

3. I work a deskjob so mayby I have to move my arm more?


Please give me some advice before I return it to the shop.

(sorry about my English)

TXS in advance Yours sincerely Adam
