No love on this forum?
The 556 stands out because it's entry-level but also serves as a solid GADA watch. The 103 stands out for its chrono qualities. Then we start moving into the specialist Sinn fliegers and divers like the 856 and the U-series with their proprietary technology. But the 104 holds this strange place, kind of like an overlooked middle-child.
My general impression is Sinn owners are either testing the waters with an entry-level GADA or going straight into the tool line and the 104 gets lost in the mix.
It's Sinn's entry level tool watch with a good selection of variants and a decent price, but it's got none of that special tech under the hood. But it's got a few things going for it - the dial and syringe hands are distinctive and the lume is great. Countdown bezel seems to be 50/50, but I personally like it. Also, when you compare the Swiss offerings in the price range, you're basically looking at Oris, Longines and TAG. The 104 holds up strong against an Aquis or an Aquaracer. Personally, besides the Aquis or 65, I don't even think it's a competition.
So where's the love?
