Head-To-Head: Seiko 5 Sport Military 100M SNZG09K1 versus Hamilton Khaki Field King Automatic H64455133

In this article, I will conduct a simple head-to-head comparison between two iconic field watches from Seiko and Hamilton, the Seiko 5 Sport Military SNZG09K1 (left) and the Hamilton Khaki Field King H64455133 (right).

 

Both have the classic field watch dial arrangement with a main 12 hour scale and an inner 24 hour sub-scale. The day and date complication overrides the 3 o'clock markers for the Seiko whereas the same set of complications overrides the 12 o'clock marker for the Hamilton. Apart from this major visual difference, there are some size differences as well. Please refer to the comparison table provided below.

It is also important to note that the caliber used for the Seiko model does not have hacking or manual winding capabilities unlike the Hamilton. The Seiko also does not use the higher quality sapphire crystal unlike the Hamilton. Instead, a small synthetic proprietary crystal called Hardlex is used.

Off the bat, it is not difficult to see the level of quality of material and manufacturing on the Hamilton when compared against the Seiko. The price point of the two watches does suggest the different level of quality between both watches. However, is the price difference justified?

I personally tend to look at the Seiko as a 'starter' watch i.e. the first mechanical watch for someone to start appreciating watches. The Seiko is an excellent gift, useful, cheap and can last literally forever (subject to periodic maintenance).

For me, the Hamilton is more like a 'beater' watch i.e. a universal timepiece that can be used in any occasion with minimal fuss. Yes, it is pricey but what you get is materials and quality of finishing generally seen on much higher priced timepieces.

In conclusion, if you have the capacity, get both.
