I do appreciate mods with a clock. Should I be undecided on which of two mods should I buy, I go for the one with a clock.
Internal battery mods make a natural choice for clocks. Few other external battery types takes a better engineering approach with an internal clock backup battery, like the the Yihi G class, or the Smok G Priv (Smok removed the clock and the backup battery on the G priv 2).
I have seen many cheap clocks lately. A proper clock requires the use of a quartz crystal for a stable reference frequency.
The crystal cost less than 10¢ and guarantees a time deviation of 1 minute / year in the worst case.
Nonetheless, the vape mods like Smoant and some Joyetech uses an RC oscillator or the microprocessor clock frequency as a time base, which accuracy is one minute - or more-- per day.
That kind of wildly imprecise clocks are not just useless, they are outright dangerous, just like the compass in the smartphones.
I carry the vape devices in places where I don't have my trusty wristwatch or my phone. Hence this is why I want a precise clock on my vape devices.
I am just disappointed with Dicodes, who do not include a clock in their devices - so they can keep with their unique zero standby current design.
On the other hand - Evolv has the most precise quartz clock in their vape mods, and some Yihi devices (if they still trade).
Smok made some very good devices with precise clock at one time, like the R80, but they since retreated into cheap average devices, leaving innovation to others... so no more good clocks from them (and pretty much anything else, I may say).
To conclude. Better not having a clock on a mod, if it isn't precise. Imprecise clocks are indicator of rushed, ported, or sloppy device design, and are a potential danger.
And, a precise clock on a vape mod, is generally an indicator of quality design, and is a feature which I welcome.
