Product Features
This genuine‑leather replacement watch strap is made for Series 1 42 mm smart‑watch. As you wear it over time, the leather gradually turns supple for improved long‑wearing comfort. Minimalist contracted‑style design delivers under‑stated daily styling.
Specially‑molded cut‑outs reserve proper space for the heart‑rate sensor; adequate opening prevents material thickness from interfering normal sensor readings. Adjustable length fits wrist circumference ranging from 130 mm to 180 mm for different‑sized wrists. Multiple color selections: Black, Brown, Red.
Important Note: Package contains watch band only. Watch connectors and smart‑watch hardware are NOT included.
