Did Spring Drive accuracy 'ruin' standard mechanical watches for you?

I'm sitting here 36 hours after setting it (my new Snowflake) and cannot see any drift, which is expected. Further, knowing the watch is insensitive to position, temperature, the tide being in or out, etc. means there is no 'luck' to just happening to keep it in the right position overnight or at the right level of wind (other than dead!). In a week, a month from now, I should start to understand what I have. I know it is rated at +/-15 seconds/month and interested to see how mine fits into that.

I ask this question partly seriously, partly in jest, but still curious as to your take. Does using a Spring Drive, which you might need to set monthly, ruin regular mechanical watches in terms of their accuracy and potential fussiness (for example, having different deviations depending on the state of wind, what position they are left in, etc.)?

Precise observations by a couple folks here have found that the Spring Drive tends to run quite a bit more accurately than the stated +/- 15 sec/mo - closer to 0.15 - 0.20 seconds per day - around 6 sec/mo or less.
Synced my Snowflake to the Atomic Clock on 1 June. It is now 7 July and has gained 9 seconds. I don't mind its being slightly fast. I, however, would not like its being slightly slow. I did advance the date on 1 July, but am thinking about not bothering with resetting the time until I change the date again.

Le mieux est l'ennemi du bien.

Warmest regards,
