STP1-11 vs ETA 2824-2

Power Reserve

The STP1-11’s design was inspired by the ETA 2824, however the STP Caliber uses a longer and thinner mainspring resulting in a boosted power reserve of 44 hours. That is 6 hours more than its ETA counterpart.

Accuracy

STP1-11 has an accuracy of -3s/day to +7s/day, resulting in a difference of max 10 seconds per day. On the wrist this would result in an on wrist performance of +/- 2 to 4 seconds as per research done by WatchGuy. This is significantly more accurate than the ETA 2824-2, depending on which grade of the 2824-2 Cal. we’re comparing with, as ETA’s 2824-2’s accuracy can vary between +/- 4 to +/- 30 seconds per day. The STP1-11 will in many cases beat ETA in accuracy.

Jewels

The STP1-11 sports 26 jewels, which is one jewel more than its ETA counterpart which contains 25 jewels. This extra jewel is used to support the top of the barrel arbor, thus prolonging its longevity as the barrel bridge can easily wear out. On this front too STP’s 1-11 is an improvement on ETA’s 2824-2 Cal.

Quality & Finishing

The quality of a movement can often be derived from the finishing and the STP1-11 can compete with the best in its class. All movements by STP come with pearlage, a Glucydur balance wheel and Côte de Genève finishing on the rotor. The Côte de Genève decoration can not be found on the standard ETA 2428-2. Lastly, all markings on the STP1-11 are better executed than the ETA, as per WatchGuy’s findings following a microscopic comparison.

Conclusion

All in all the STP1-11 can be seen as an improvement on the watch industry’s beloved ETA 2824-2. It has all the things we love, appreciate and have gotten used to… But even more. Added longevity, better finishing, slightly better accuracy and a bigger power reserve.
