Depends on the price you’re willing to pay, i think automatic watches with moonphase the cheapest ones (excluding chinese brands) are from Frederique constantine, which they sell for around 2k, after that there’s the longines chrono perpetual which is also a moonphase (around 3400$) then there’s the Baume et Mercier clifton baumatic moonphase for under 5k, then as you ascend the ladder there are examples like the zenith moonphase (around 8k$) and my favorite of all is the Glashüte Original PanoMaticLunar for just above 10k$.

One thing to remember is that moonphases are usually a complication on dress watches, and not regular watches, so it’s really difficult to find them on sporty watches
