We present the status of our optical clock based on Ramsey-Bordé spectroscopy using the 1S0 →  3P1 intercombination line at 689 nm in strontium. We give an overview of the underlying spectroscopy principle and a clock instability and uncertainty budget. Further, we present the current status in the laboratory including the design of a new compact and high-flux atomic oven and our work on the spectroscopy setup. Lastly, we show our progress towards micro-integrating the setup.
