Hello OF Mods, Considering the plethora of variations, rampant redials, and widespread fascination, I feel that a sticky thread, dedicated to 13ZN inquiries, may be in order. There have been quite a few threads about 13ZNs of late. A centralized (sticky) thread may become a valuable resource if this trend continues. However, I do not know what the creation of a sticky thread entails and therefore respect your judgement on the matter. The first is surely a redial with a very poor signature. The second looks suspicious to me as well. The large numerals are in a font that is usually found in much older watches and the open minute track, with round 3s and a closed 6, seems odd too.
