Sinn is one of those brands that are synonymous with quality and reliability.
Extremely well built, purposeful and made to last.
The 556 is in my opinion one of their best products despite being the entry level watch. Maybe because of that exactly. It has so much quality for what it costs that it's amazing and a fantastic product.
Stainless steel case with 38,5mm , sapphire crystal glass in front, anti-reflective on both sides, transparent case back also in sapphire, anti-reflective on the interior, screw case back and crown and meets the technical requirements for waterproofness, as set out in standard DIN 8310, waterproof to 20 bar.
The dial is the most striking feature of this watch, an amazing matte black with white indexes and numerals highly legible compliment with a sword shaped pair of hands also in black and white. Discreet round date window between 4 and 5 o'clock.
This watch comes as a full set, all boxes and papers. Also has a full length metal bracelet and the original Sinn black leather strap. Condition is very good.
