Longines Watch
Longines uses ETA and Valjoux movements (both Swatch Group in-house) that have been refined over decades — the L888 automatic movement in the Master Collection runs at 25,200 vibrations per hour with a 72-hour power reserve and is rated for chronometer-level accuracy. The sapphire crystal is second only to diamond in hardness and won't scratch under normal wear. 316L surgical stainless steel cases resist corrosion. With regular servicing every 5-7 years (cleaning, lubricating, and replacing worn gaskets), a Longines runs indefinitely. The brand has been in continuous operation since 1832.
