Just to update the thread, one year after my first Rolex purchase after receiving a nice tax refund I am waiting to receive a DD40 WG silver dial like this:
I think that I will not use much the DJ36 once I receive the new one and I have considered to sell the DJ36, but the dealer made me an offer that I can not accept and in the country where I live there is not a good secondary market, therefore I will keep it and I will reconsider it in the future.
