I acquired a Cosmic from @Toishome. Nothing special but certainly a fair price. I was planing to us this as a daily beater. Positively surprised when it arrived. Then some time later I found out that the date ring was not running. No idea whether this was caused by the shipment or not. Because of COVID everything a bit difficult. The seller said immediately "send it back at my cost and I will reimburse". I was a bit stubborn and decided to bring it to my watch maker. Two parts (not cheap at all) appeared to be broken. Seller was very flexible and we split the costs. So I can recommend seller without doubt!
