This is part 3 of a three-part series about Derek Pratt’s reconstruction of John Harrison’s Longitude Prize-winning H4, which was the world’s first precision marine chronometer. This article was first published in ‘The Horological Journal’ (HJ) in April 2015, who we thank for graciously granting permission to republish on Quill & Pad.
Here we present the second part in a three-part series about the making of Derek Pratt’s reconstruction of John Harrison’s H4. This part was written by Carl Murray of Frodsham.

Here we present the first part in a three-part series about the making of Derek Pratt’s H4 reconstruction. This part was written by Roger Stevenson, chief watchmaker at Frodsham.

In the world of watches, especially with regards to collecting, rarity is a large factor contributing to the cost of a luxury timepiece. The reason is because rarity is almost always an implied condition that seems beyond control – like it just happens. In this article Joshua explains why he thinks that out of all the metals, especially the white metals like platinum and white gold, stainless steel is absolutely the most precious metal.
Ulysse Nardin is the watch world’s pioneer in “new” technologies. Though it might seem anachronistic that a 163-year-old company famed for its marine chronometers would be the one to start a revolution of this type in mechanical watchmaking, that is just what Ulysse Nardin did by leading the search for the perfect materials and advanced geometery. Here we take a look back at the technologies leading up to the introduction of 2007’s InnoVision and why that particular concept watch was so notable.
The retrograde indication is one of my favorite “Because We Can” (BWC) complications. Gears are an amazing invention and have allowed watchmakers to make incredible creations. Simple gear systems leave a multitude of openings for creativity. Look at some great examples of it here!
Marketing material for the modern mechanical watch almost always includes a description of the the movement’s frequency. You may have even sensed that the higher the frequency, the more accurate a movement gets. But is this entirely true? Find out here.
Waxing poetically about moon phases has gotten me excited enough to take a trip through certain “phases” of engineering excellence . Here we bring you the eight most accurate moon phases currently fitted into a wristwatch. Join us on this odyssey through space and time.
Timepiece repairs can be expensive and often take a long time, so you generally want to avoid damaging a watch. It’s obvious that throwing your watch against a wall, running over it with a Bentley, or smashing it with a hammer are things to to avoid. However, not everything that can damage a watch is so obvious, so here I list five common things you may not be aware of that can damage a watch and how to prevent them.
Imagine my surprise when, in one of my rare predictions about the future of 3D printing in watchmaking, I got one right: the Panerai Lo Scienziato Luminor 1950 Tourbillon GMT Titanium says it all. It is (as far as I know) the first production watch to utilize 3D direct metal laser sintering (DMLS) printing for the case construction. The case is made of titanium for extra lightness, but that’s not the only, or even the main, reason for using DMLS titanium.
