Case designs and measurements to start manufacture of case.
Solid stainless billet.
Initial guiding hole drilled out.
Further drilling.
Another detail of slow drilling process of stainless steel.
Drilled through hole.
Opening the center hole.
Further opening of center hole
The machining is done by slow turning, no coolants are used.
Center hole turned.
Bezel area was turned.
Area to be removed to manufacture the bezel.
Initial cutting with a saw.
Further cutting.
Bezel material cut.
Main portion and bezel were faced off.
Cutting of sides.
Rough cut by saw.
Other side being cut.
Rough cut billet to be squared.
The rough billet is placed in the lathe, and an outer, larger diameter turned.
Diameter turned to ca. 47mm. Used as initial guide for squaring the billet.
Placed on mill to create parallel sides to the billet.
Milling taking plae.
Further milling.
Top and bottom are aligned to within 10th of a millimeter.
The rough shape of the lugs are going to be milled out.
Rough milling of first lug area done.
Further milling of internal lug area.
The position of the case is then changed and end milling takes plae.
Further rough milling.
The three cases have been given their internal lug areas (preliminary).
Placed against a coordinate drawing, and a stencil in order to mark out general lines of case.
Placing on the mill the first lug is to commence.
First lug milled out.
The position of the watch case is changed and work on the second lugs takes place.
After many passes of the end mil the rough shape of the case is milled out.
The case is placed on the lathe and the final diameter of the case turned as a reference point.
Three watch cases waiting further work.
The case is being milled closer to the final measurements.
Continued milling.
At half a millimeter from final measurements.
The interior lug space is filed by hand.
The first lug space is finished, the interior diameter is 20mm, and will be opened to 22mm once the case is nearly finished.
The other lugs are marked for filing.
Top left lug corner is finished.
All interior lugs spaces filed to within .5-1mm. They will be finely finished at a later stage.
The case is placed on the lathe and the movement seating is turned.
Turning the case goes slowly as the swarf needs to be cleared after every cut.
Turning the smallest diameter, which is the very bottom of the movement seen through the display back.
The smallest diameter is turned to measure, it will be polished at a later stage.
Turning now the top portion of the movement seat.
Further turning of the top movement seat. There are three different diameters to be turned inside the case.
Checking the top movement seating.
The movement set in the case. Further turning will be done so that the movement sits 1mm deeper into the case.
The top of the case area is cleaned.
Look at the side area that is to be reduced.
The top of the case is further cut.
The case is reduced.
The lug shape is marked out roughly.
Turning the lug shape.
Lug rough shapes cut.
Cutting the 'snap on' bezel groove on the case.
Further cutting of interior groove to have the lip snap on.
Lip cut.
Turning the back of the case to size.
Further turning.
Further turning, there is about 8 mm to be reduced.
The back opened.
Checking movement seating and opening.
Starting to reduce the bezel for the Guye watch.
Working on the interior area of the bezel for the snap on groove.
The bezel is reversed and turned to outer diameter.
Turning to rough thickness.
Turning the initial opening for the crystal.
Checking fit for the crystal.
Bezel is reversed and further work on the snap on bezel.
Turning the outer initial lip on the bezel around the crystal.
Further turning of the case back to size.
Rough look at the case back. It is at a larger diameter than final diam of 44mm.
Very rough look (all measurements of bezel and case slightly larger than final.
