DekaClock
Read full descriptionHide full description
Did you ever notice, the time of the day is based on odd numbers? So, a day is split into 24 hours, an hour is split into 60 minutes and a minute is split into 60 seconds. Strange, isn't it? Since in many cultures nowadays our numbering system is based on the base of 10, the usual time structure as stated above, leads to some strange counting artefacts. DekaClock attempts to solve this by introducing a time-system strictly based on the base 10. The different tiers required will not be named hour, minute, etc. to avoid confusion, but rather "deka-1, "deka-2", ..., at least until a better naming comes up. "Deka" is the greek name for 10, so the name is very suitable. Since the duration of a second is a very tangible and the shortest time-period in the traditional time scheme, the DekaClock needs to come up with something similar. A traditional day has 24 * 60 * 60 = 86,400 seconds. So, the DekaClock day has 100,000 deka-5 periods, since ist has to be a number by an integer power of 10. Naturally by this, the DekaClock scheme has 5 tiers to give an accurate time of the day: deka-1, deka-2, deka-3, deka-4 and deka-5. A deka-5 period therefore is slightly shorter than a second, concretely 0.864 seconds. But this is close enough to "feel" the ticking of the clock correctly, as the passing of time in DekaClock shows. To give the full time of the day, consequently 5 single digit numbers from 0 to 9 are required. They are given separated by a colon each. For example midday is 5:0:0:0:0, 6am is 2:5:0:0:0 and 6pm is 7:5:0:0:0. So, a deka-1 period of time is a tenth of a full day of 24 hours, thus encompasses 2 hours and 24 minutes. The time of day "9 deka-1" as example refers to 9:36pm on our standard clock. A good time to go to bed.

Experience the elegance of traditional horology on your wrist. Repeater brings one of watchmaking's most revered complications to Apple Watch and iPhone: the minute repeater. With a simple tap, hear the current time announced through authentic chimes recorded from early 1900s pocket watches and classic mechanical timepieces, or fun sound packs like a kid's bike bell. THE MINUTE REPEATER Before electric lights made reading watch faces easy, minute repeaters solved a practical problem: telling time in the dark. By pressing a slide on the case, the watch would chime the hours, quarter-hours, and minutes through precisely tuned gongs. Repeater honors this tradition with a decimal system optimized for modern timekeeping: Hours chime with a distinct low tone Tens of minutes sound as melodic ding-dong pairs Individual minutes ring with a higher chime For example, 3:25 plays as: three low chimes (hours), two ding-dong pairs (twenty minutes), then five high chimes (five minutes). AUTHENTIC AUDIO Unlike synthetic sounds, Repeater uses professionally recorded audio from real mechanical timepieces. Each strike captures the warmth, resonance, and character of genuine watch complications — delicate pocket watch bells to robust wristwatch gongs, to a fun kid's bike bell. Multiple sound packs available: Pocket Watch Repeater (included) — Early 1900s pocket watch with warm, intimate tones Bicycle Bell (included) — Playful thumb bells for a cheerful experience Tower Bells (included) — Classic church bell tower sound, loud and expressive Wood blocks (included) — Dry hardwood temple blocks, subtle and warm Classic Repeater (premium) — Two options, recorded from a traditional wrist watch with refined chimes WATCH-FIRST DESIGN Repeater is built primarily for Apple Watch, putting the complication where it belongs: on your wrist.

Verdict
The clearest difference is in-app purchases: DekaClock at none against Classic Repeater's 1. DekaClock also leads on update cadence (every 2 months vs every 6 months) and iOS requirement (16.0 vs 26.0). On price, ads and device support there is nothing between them.
