Multi-epoch spectroscopy reveals an orbital period of 109.20279 minutes, consistent with TESS and ZTF photometric data, marking it as the sixth detached system known to harbor a WD companion with a period less than two hours. J1710 is remarkably close to Earth, situated at a distance of only \\(350.68^{+4.20}_{-4.21} \\, \\mathrm{pc}\\), with a GAIA G-band magnitude of 12.59, rendering it conducive for continuous observations.
