Usually there is a circuit to protect the battery from doing so, so it shouldn''t do so. But sometimes you want to go even lower than the charging circuit max, which is my guess for when the low charge mode comes in. Taking 2-4 hours to charge the watch would make it last longer than charging in 0.5-1 hours.

Our chargers come with multiple low-power modes to help maximize battery runtime and stand-by time for the maximum charge and a battery that’s instantly ready for use. Learn more about battery chargers that support USB-C and USB-C PD power levels and enable charging and discharging from the same USB-C port.
Designing a power path battery-charging IC enables you to maximize its lifetime by shutting off the battery FET – powering the system directly from the adapter and preventing the system from using the battery for power eliminates the need to discharge and recharge the battery.
The termina-tion is based on the ratio of charge current and preset constant current (Fast Charge). If the system draws current from the battery, the charge current will never meet the termination value. This causes the non-termination of the charge management circuit.
Most Li-Ion battery chargers are based on Constant Current and Constant Voltage (CC-CV) modes. The termina-tion is based on the ratio of charge current and preset constant current (Fast Charge). If the system draws current from the battery, the charge current will never meet the termination value.
In a lithium-ion (Li-ion) charging profile, the charge current tapers down during the constant voltage phase until it reaches ITERM and then shuts off. In order to maximize the battery capacity, it is important to have a low ITERM and the ability to accurately measure low ITERM values to precisely terminate charging.
An external sense resistor can set the maximum charging current. The devices feature an operating current of only 560μA (Max). A shutdown mode is also available for reducing the total current to less than 15 A. Both 4.1V and 4.2V μ voltage options are available to accommodate Li-Ion batteries with coke or graphite anodes.
