A refined take on Japanese watchmaking, the Knot Mechanical Open Heart combines elegance and engineering in a versatile 38mm case. Crafted from polished SUS316L stainless steel with a sapphire crystal and non-reflective coating, this timepiece reveals its beating heart through an open balance wheel at 9 o’clock. The burgundy red dial shimmers with subtle detail, complemented by silver hands and Roman numeral indices. Powered by the reliable Epson YN84 automatic movement (22 jewels, 21,600 vph, 40-hour reserve), it maintains precision within -25/+35 seconds per day. Finished with a slim 11.3mm profile, 5ATM water resistance, and weighing just 53 grams, it’s the perfect blend of dress watch sophistication and everyday wearability.
