Sealander SH21 ???

Post by 5oclockhero »

So nice to see the SH21 movement being promoted again. I have often wondered why CW don't make more use of it given the general enthusiasm many other watch manufacturers have for being able to boast of using or making an in-house movement.
Given the popularity of the Sealander range, I wondered who else would like to see a C63 SH21 in future? Would the SH21 fit into the 39mm case? The smallest watch that I know of with SH21 is the C1 Morgan watches at 40.5mm,
those are priced at £1800. Maybe if the power meter was omitted, CW could bring a C63 SH21 in under £1500, and go head to head with the Nomos Club Campus range of in-house watches (which are currently the cheapest European-made in house watches I can think of.
This would hopefully bring the SH21 to a much wider audience and enhance the CW brand even further. What do others think? And are there engineering difficulties in achieving this?

I think the SH21 is too large for the current C63 cases. Maybe if there are larger cases in the future then it will be a possibility. But the mood music from CW seems to suggest that smaller C63 cases are more likely than larger ones in the short term. But who knows? I don't have any inside info on this.

I'm certainly a big fan of the SH21 (I have four watches already with it and a Concept ordered too), so any new model with this movement would interest me :thumbup:

Not sure if they could fit it into the C63 cases (as welshlad says) though :problem:

Interestingly, the recent CW article (link below) about the C60 Concept states that there are "around 8000" SH21 movements "out there in the wild"... that's a significant number and so they must now have good solid information about it's reliability and serviceability too.

I thought that the SH21 is a 13 linge (30 mm) movement. If so that could fit into a smaller case. Oris put the 400 calibre into a 38mm case.

I have no watchmaking knowledge but before posing the question I tried looking up the SH21 caliber on a couple of websites, and although information is a bit scarce, one suggested a diameter of 32mm for the movement. I considered the external size of the C1 is less than 2mm greater than a C63, so although allowing for case material thickness I thought (hoped?!) the SH21 might squeeze in a C63.
Maybe someone with both models could get the micro-screwdriver set out and give it a try ? Only joking.... :lol:

Hmm, yes, I'm sure I heard Mike French describe it as "not a small movement".

I think CW have previously said that the smallest case a SH21 can fit into is 40mm.

I know that a Unitas 6498/7 which is 16 linge (36.5 mm) can fit into a 40mm case. Both Tourby and Zeno list model in a 40mm case with that movement. I have the Zeno it does look a tight fit but it works.

Pretty sure I remember mention of a smaller SH21 at some point in the future- though I might have misheard / misunderstood. That would open up lots of new opportunities but I imagine is not a straight forward redesign.
