Sadly. no. The "depth" quoted by all watch manufacturers in their water resistance claims has nothing to do with a physical water depth, but is instead indicative of the static pressure used during the successful pressure test.
Actually waving your arms around under water creates a dynamic water pressure far in excess of the static pressure extered by that depth of water.
For swimming (not diving) watches marked 100m are ok. But only as long as you don't press any of the buttons.
For button-pressing in a pool, or anything more demanding, including SCUBA, 200m marking should be the minimum considered, and even then I would get a watch that explicitly claims to be suitable for diving.
