[en] We present new measurements of the time delays of WFI2033-4723. The data sets used in this work include 14 years of data taken at the 1.2 m Leonhard Euler Swiss telescope, 13 years of data from the SMARTS 1.3 m telescope at Las Campanas Observatory and a single year of high-cadence and high-precision monitoring at the MPIA 2.2 m telescope. The time delays measured from these different data sets, all taken in the R-band, are in good agreement with each other and with previous measurements from the literature. Combining all the time-delay estimates from our data sets results in ∆t[SUB]AB[/SUB] = 36.2[SUP]+0.7[/SUP][SUB]-0.8[/SUB] days (2.1% precision), ∆t[SUB]AC[/SUB] = -23.3[SUP]+1.2[/SUP][SUB]-1.4[/SUB] days (5.6%) and ∆t[SUB]BC[/SUB] = -59.4[SUP]+1.3[/SUP][SUB]-1.3[/SUB] days (2.2%). In addition, the close image pair A1-A2 of the lensed quasars can be resolved in the MPIA 2.2 m data. We measure a time delay consistent with zero in this pair of images. We also explore the prior distributions of microlensing time-delay potentially affecting the cosmological time- delay measurements of WFI2033-4723. Our time-delay measurements are not precise enough to conclude that microlensing time delay is present or absent from the data. This work is part of a H0LiCOW series focusing on measuring the Hubble constant from WFI2033-4723.
