At this price range you can get a very respectable and dependable watch and be very picky as well for whatever style you want. At this range the standard will more than likely be sapphire crystal and an automatic movement but again this heavily depends on the brand and what they set their standards at. These are just my personal recommendations and all prices are in USD.
Phoibos Wave Master PY010C ($299)
For the price and what is being offered and I have not heard anyone complain about their Phoibos once they purchased it, especially not about its build quality. The obligatory comment of “Hail Hydra” under every post of its watch is mostly due to their logo. It is a dive watch made out of 316L stainless steel featuring a water resistance of 300m and a unidirectional ceramic bezel. It also features Super-LumiNova Dark Blue and BGW9 on the hands, indices and bezel markings. The dial features a distinct wave pattern which explains the name and is powered by the NH35 automatic movement.
Hamilton Khaki Field ($495)
This price is only through Hamilton’s own online store, but if you were to shop around you can find this watch around $400. If you are looking for a reliable brand and one of the most well-known field watches, this watch should be on the top of your list. It comes in a case size of 38mm, features sapphire crystal and the movement is Hamilton’s H-50 automatic movement that has a power reserve of 80 hours. While the water resistant is not that great at 50m, you do get a brand with some heritage and an excellent field watch.
Junkers 9.09.01.02.M 40mm Series 100 Years Bauhaus ($290)
This is in the Bauhaus style and it comes in a case diameter of 40mm. This is the price however that is available through them directly, it is very easy to shop around and find it for a much cheaper price and even better specs. It features the Miyota 1L45 quartz movement and also has Hesalite glass as the watch crystal. While extremely durable and impact proof, the scratch resistance is quite low. However, the scratches can be very easily buffed out and the glass compliments the style of watch perfectly and even at higher price ranges it is common to see Hesalite used for these types of watches.
Timex Celestial Opulence Automatic Ladies Watch ($249)
An absolute steal at this price as to what is being offered. You get an automatic movement with a 40-hour power reserve, with an exhibition case back. The dial features an open-heart moon that showcases even more of that movement. It comes in a dual black and gold tone watch, while the dial is black with starlike texture in the middle, the rest of the hour markers and hands as well as the case is in gold-tone. The crystal however is acrylic, while not as scratch resistant as sapphire or mineral it is extremely durable and impact-resistant and the scratches can be easily buffed out.
Tissot Carson Premium Lady ($325)
If you are looking for a more minimalistic watch but still has an excellent look the Tissot range of women’s watches are worth looking into. This particular watch is available in several colourways, this one however comes in a silver sunburst dial, roman numerals and blue hands to create a beautiful contrasting effect between the dial and hands. It is made out of 316L stainless steel and comes with sapphire crystal but unlike the previous one it is a quartz movement. However, it has an EOL indicator to let you know when the battery is almost out.
