Series 1 vs Series 2 Haptic Strength?

[stevefo]

Is there a difference between S1 & S2 haptic strength? Is it stronger on the S2?

I can't tell the difference between the models I own. But some forum members are reporting there apparently is a stronger Haptic in the S2. I think also depends on what level of Haptic the Watch is set on to decipher this.
