Continuing this theme, here is a Raketa 2609.HA from the mid 1970s immediately post-op, and the same watch some 12 hours later, both dial up.
The big balances in these 1800bph movements make for some nice stable traces, and allowing everything to bed in has improved the picture immensely. Nothing has been done to the watch between the first graph and the second, other than wearing it on my wrist for a few hours, and letting it sit overnight. The improvement is entirely down to the fresh lubrication doing its work.
You mean from the outside pressing in? A men watch doesn't even fit vertically under the stake. Then, some tubes have a step and won't leave in that direction. https://www.cousinsuk.com/product/box-sets-of-tube
