Missing sleep phases
-
Recently I’ve started using a Suunto Vertical again, and I’ve noticed that during sleep tracking it seems like the different sleep stages are no longer being measured correctly. I also have a Vertical 2, and on that device this works fine. Is this a known bug with the Vertical?

@Robbin053 This is not a bug, Vertical 1 does not have sleep stage analysis, except deep sleep.

Ah okay, my mistake—I thought the original Vertical had the same sleep tracking as the Vertical 2.

As a matter of fact it means that VS has at least two sleep stage analysis: deep sleep and everything other than deep sleep:)

@Ars-Vitae Ik begrijp niet waarom Suunto het slaapgedeelte zo beperkt op de Vertical. Ik heb het horloge indertijd 550 euro betaald en voor dat geld mogen toch wel alle slaapfases vermeld worden. Tegenwoordig kan een goedkope Chinees horloge dit al perfect voor minder dan 100 euro.
Dus Suunto doe een firmware update en maak dit mogelijk aub.

@Philip I think it was mentioned somewhere that the sleep tracking is part of an ‘external’ agreement with a 3rd party provider of the metrics (this was true for all the watches prior to the Race). Now all the watches have an in house metrics. I might be speculating but if the agreement between parties has some cancellation clause that is not in favor of Suunto it is very difficult to cancel the agreement and just replace it with the in house.
What is now seen as a disadvantage, once we lived in world where you would outsource some functionality so other companies would benefit and share the wins. After recent years that competition is non-healthy and big companies buy out smaller ones and use their portfolio to put pressure on others we live to see the results
(Just my thought - it might be wrong) -
@Philip A €100 watch can display many metrics, but that doesn’t mean the data quality is comparable. More numbers do not necessarily mean better measurement.
We don’t know exactly which computational models Suunto uses on the Vertical 1.
Sleep and HRV algorithms are strongly tied to the hardware, especially to the OHR sensor and signal quality.
The Vertical 2 uses different hardware and a different optical heart rate sensor.
It is plausible that any algorithmic evolutions are designed around the newer sensor and are not backward compatible with the Vertical 1.
For this reason, realistically, it is difficult to expect major new implementations on the V1. Future developments are more likely to focus on the newer hardware platform.
The price of the device is not the decisive factor. The hardware architecture is.
EDIT: From the photos, the Suunto Ocean sensor appears to be the same as the one in the Vertical 1, and the Ocean does report deep, REM, and light sleep stages. So, in theory, the Vertical could inherit those features.
That said, I may be oversimplifying. Even if the hardware looks similar, firmware architecture, signal processing, and model calibration can differ significantly between devices.
