Hopefully some of the experts on this very impressive forum can help me with the following: I have a one year old 16600 Sea-Dweller, which has just been pressure tested at a local watch maker (not AD). The pressure test showed, that under the compression test everything was fine, but under the decompression test it failed. My question is: Is the failure to pass the decompression test due to the HE valve? In other words: should a SD always fail a decompression test because of the HE valve?

thanks for your answers in advance

best
