Here are four of the best watches we've found this month

Special calendar tech is only pricey if it’s mechanical. A quartz movement in this G-Shock has no problem keeping the correct date. This collaboration with the Toyota Auto Body Dakar team comes complete with faux muddy strap.

Date night: get yourself a mechanical watch that tells the time *and* the date

If a perpetual calendar is beyond your budget, an annual calendar is next best. This Longines will only need adjusting once a year (the end of Feb) and has an alligator leather strap and an automatic movement in a 40mm stainless steel case.

IWC has also been in the ‘perp cal’ game a long time. This new version of the Portugieser perpetual calendar features a 44mm case that comes in a variety of different golds and dial colours. Automatic movement with seven day power reserve.

There is not much Patek doesn’t know about perpetual calendars, first putting one in a wristwatch way back in 1925, when the wristwatch itself was only just a thing. With moon phase and windows for day/night and leap year indicator. Auto movement in 41.3mm platinum case and hand stitched alligator strap.
