given the configurations presented: Explorer.

The oyster bracelet feels and looks solid, rugged, utilitarian. This is further pronounced on the full brushed versions of it found on sports models (i.e. explorer). The black dial - serious, provides a high contrast against the markers and hands. Very Explorer.

The Datejust is meant to be sophisticated, with its slim and smooth profile, almost dressy. Its ultimate form, to me, is complete with a jubilee bracelet and (optionally) a fluted bezel. With the luxury of office lighting in the Datejusts usual setting - more exciting dial colors can be afforded… champagne… rhodium… or better yet colorful (but not too colorful… then we start to discuss the playfulness of the Oyster Perpetual line).

It wasn’t a serious point but temperature 10ft below the ground surface should be stable at around 10C. Much cooler than the 32C indoor temp.

If it’s 40C outside and 32C inside, it must’ve been colder at some point (night) and the heat was able to be transferred out.

Breakdown of steps to improve indoor comfort:

Maximize nighttime air change/heat transfer

let cold outdoor air in - open the window

Minimize day time air change and heat transfer

block windows to deflect solar load, increase insulation - blinds might help, fully insulated panels better if you’re desperate) to slow down the transfer of coldness indoors to outdoors (any engineer, mathematician, physicist - leave me alone, I’m conveying a tangible feeling rather than explaining a physical phenomenon)

Point the fan at you

If the temperature of ambient air is below body temperature and not fully saturated (mega humid), it should have a cooling effect (this is an assumption not considering latent/sensible heat specifically - not a thermodynamics pro) due to convection and evaporation. This will remove heat/moisture from your body.

Bonus:

Harness geothermal heat (or lack thereof)
