Laser cooled atomic clocks allow to both extend spectroscopy duration and better control the systematics. We present a commercial microwave clock that achieve an extreme stability of 3.2×10 -13 at 1 s and 1×10 -15 in less than 2 days, with a turnkey product dedicated for continuous long-term operation.
