Tissot Visodate T0194301605101 ($400)
A great dress watch and features a lot of the same as what you would expect from this price range. It is an automatic watch and also features an exhibition window. The crystal however is a domed mineral crystal, and there has been some reviews saying that the crystal is a bit too reflective making it hard to read. However, for the style of the watch as well as the price it is a genuinely good watch.
Hamilton Khaki King ($350)
You can usually find this watch around this price range, and is an absolutely amazing watch. It features Hamiltons own automatic movement calibre H-40 with a power reserve of 80 hours. The style would be more towards a field watch and it comes with sapphire crystal for the glass of the watch. It also features a lume for the hands and markers. The back of the watch also features an exhibition caseback so that you can see the movement of the watch.
Junkers 9.08.01.02 ($230)
This is in the Bauhaus style and it comes in a case diameter of 40mm. The glass is described as hesalite glass, meaning this is a form of plastic/acrylic. Therefore be wary of scratches, and if it does get scratched however you can repair it yourself. It does come in stainless steel and also features a quartz movement, however for the price getting a Bauhaus style of watch is an incredibly good deal.
Movado Musuem Women’s Watch 0607206 ($400)
A very elegant and classy watch, a unique design by Movado is that they do not put any hour markers other than the 12 hour marker in which they put the Movado dot. This gives arguably the watch that embodies the style of dress watches the most. At this price range for this watch model it does have a rose gold PVD bezel, however it should be expected at this price range for dress watches not to use precious metals. It is a quartz watch, but there is no second hand meaning no one will be able to tell if it is quartz or mechanical if that is a concern for you.
Seiko Presage SRRY035 ($450)
This is advertised as a ladies watch with a case size of 33.8mm. This watch has an amazing textured dial with also an open heart design on the watch. The open heart shows the balance wheel of the watch through the face of the dial. It has hardlex crystal which Seiko say is more durable than mineral. It is also anti-magnetic meaning you do not have to be careful of magnets damaging the components of the watch. If you want a larger case size go for the model number SARY155 as this is the men counterpart of this model with a case size of 40.5mm.
