Moon phase watch options without breaking the bank..

Really depends on budget - it starts from very cheap at the Chinese end and you can end up with a Moser & Cie (with aventurine :P ) on the other side (it is a lovely moonphase though).

It's for the other half so perhaps something more feminine?

Here are some of the cheaper (but still good) Chinese options that I know of:

- 150-160 euro - that lovely ST1908 mechanical column wheel chrono - and date and moonphase in a quad compax dial.

if you really want to go all out for a moonphase I believe this is an expensive homage of an even more expensive Swiss brand:

- but man it's all about the moonphase here - and it's not exactly "cheap" for a Chinese watch - the Swiss version I believe is a lot more expensive though.

Pseudo German aside - this actually looks like something Moser might have produced:

pretty much all about the moonphase too - not expensive for new but I have no idea if it's a reputable brand or not - the aesthetics look good to me though.


And here's a Swiss option for less than that Agelocer:

Quartz (but again lots of ladies like that option) - MOP dial and maybe diamond(?) indices, with the moonphase.

Something like this?

Orient Sun & Moon?

And a +1 for the Balticus - they are a very well known and reputable microbrand out of Poland. And indeed they have offered aventurine on their dials also for some time too.

This particular model uses a Ronda quartz movement btw (just in case guys were searching for automatics only).
