#marine chronometer

Two day marine chronometer used and owned by Captain Robert Fitzroy on board HMS Beagle in 1828.

📅 Wednesday, August 5, 2026 While Switzerland is synonymous with chronometer certification today, the first watch to officially receive a chronometer certificate was actually an English pocket chronometer made by John Arnold in 1779. His No. 36 chronometer was tested by the Board of Longitude and proved remarkably accurate, paving the way for precise marine navigation and the later establishment…

John Harrison's Marine Chronometer.

You see, we have looked at this watch before – or it’s forbear, at least.  Back in 2012, it was known as the Offshore Professional Field Engineer, and now it’s known as the Marine Chronometer Co Field Engineer.  Under the old name (and style) we did do our own hands-on review, which you check out here (part 1, part 2, part 3).  This time around, due to them being built-to-order, we’re just talking about the new watch.

And you might wonder, well, why is Patrick talking about a chronograph?  Back when I checked out the older version, I really got to liking the piece, even if I wasn’t particularly using all of the functions.  Here, we’ve got the same sort of functions (base is still the Valjoux 7750), but there is a very noticeable change – the day/date windows.  These are custom to the brand, and presented just below the logo (ie, where you’d normally expect the date window to pop in).

In my opinion, the new dial configuration of the Marine Chronometer Co Field Engineer is an improvement over the original as well.  It’s still got the dimensionality and layers, but we’ve got some additional color popping in.  I’m also a fan of the tachymeter bezel being added (though you can get the Roman numeral one instead if you like, and am really glad the knurling stayed present on the crown and pushers.

At the end of the day, the asking price of £1650 (~$2,300) feels pretty reasonable – as we said before – for what you’re getting here.  Particularly for the fact that the fellow behind the brand, Lorne Gifford, is actually traveling the world as a field engineer (hey, look at that title!) and putting his watch through some more extensive paces than we might actually put the watch through ourselves (some photos of that are in the gallery below).  So, if you’re in the market for a small-brand chronograph with a storied movement in it, the Marine Chronometer Co Field Engineer should be on your short list to check out.  marinechronometer.co.uk

Watch Overview

Brand & Model: Marine Chronometer Co Field Engineer

Price:  £1650

Who we think it might be for: Well, for field engineers, for one.  Or for anyone who wants a chronograph from a small brand ready-built to handle whatever you can throw at it

Would I buy one for myself based on what I’ve seen? Probably not, since I’m not much for chronographs

If I could make one design suggestion, it would be: Wouldn’t mind seeing what Gifford could do – in this design language – for a GMT (I mean, he is a traveller!)

What spoke to me the most about this watch: All the thought and effort that goes into the creation of the watch (seriously, check out the details on their site)
