This version of the Omega Seamaster 300M Mid-size Quartz is gaining in popularity. I regularly have people message me about it, so let’s jump in. I went with the midsized version, which clocks in at 36.25mm. The lug-width is 18mm. Lug-to-lug length is 43mm and thickness is 11.2mm. This SMP is definitely wearable. It’s light, looks great on a number of straps, and is small without looking diminutive.

The movement is Omega’s Calibre 1538, which is running +12 seconds per year. It features a jump-hour setting, which allows for easy time changes when traveling through different time zones. The lume on the Omega Seamaster 300M Mid-size Quartz is the best I’ve seen. While I love the brightness and duration of the lume, at times, the color can appear to be what I’d describe as “mucus-green.”

The water resistance is 300m, which is plenty for any situation I may find myself in, such as intense dish washing, ice-bucket challenges, etc. The threading on this crown is absolutely phenomenal and one of those small details that I appreciate on the Seamaster 300M Mid-size Quartz. While I don’t mind the Helium escape valve, I’ve heard it referred to as a wart on the side of the case.

The dial of the Seamaster 300M Mid-size Quartz has a wave design, which adds a bit of visual interest. There are parts of the dial that are less than perfect. For instance, in the 11 o’clock lume plot, there is a speck, as if the lume wasn’t fully filled in. I’ve seen these things on other pictures of Omega watches from this time period, so I’m assuming it’s a QC issue.

The bezel is my only real complaint. These scalloped bezels are notoriously challenging to manipulate. This one is no exception. While I don’t dive, I do regularly use my dive bezels to measure random things. If you like dive watches, but not necessarily the size of dive watches, or you want a Seamaster, but the modern ones don’t quite do it for you, this Omega Seamaster 300M Mid-size Quartz may be the one you’re looking for!
